TIRE INFLATION PRESSURE

Tires can lose 1 psi (pound per square inch)

per month under normal conditions.

Additionally, tires can lose 1 psi

for every 10° F temperature drop.

This chart shows you how underinﬂation

can create an overload on tires

Check your tire pressure every month to make

sure it’s up to specication, especially before

long trips or carrying extra weight.

Look for the manufacturer’s recommended

tire pressure listed on the sticker usually

located on the driver’s-side door edge or

door jamb area. Example:

Just a look won’t do it.

One of these tires is actually 10 psi

under-inﬂated. Your eyes can deceive

you, so rely on a good tire gauge for

an accurate reading.

MONTHLY CHECK

For accuracy, check your inﬂation pressure

with a tire gauge when tires are cold.

Driving heats up tires and makes the

reading incorrect.

TIRE ROTATION

For maximum mileage, rotate your tires

according to the vehicle manufacturer’s

recommendations (consult your vehicle

owner’s manual), or if not provided, rotate

every 5,000 miles using a rotation pattern such

as below (see “Radial Tire Rotation” in this manual).

TIRE WEAR–VISUAL CHECK

Check for obvious signs of wear.

Place a penny in the tire tread

grooves as shown.

If you can see the top of Lincoln’s

head, the tire is worn out and

needs to be replaced.

a) Remove tire valve cap.

b) Place the end of the tire

gauge over valve.

c) Press the tire gauge

straight and rmly until

the scale extends.

d) If needed, increase

pressure and recheck

with the tire gauge.

TIRE MAINTENANCE AND

SAFETY INFORMATION

Any tire, no matter how well constructed, may fail in use as

a result of punctures, impact damage, improper inﬂation,

overloading, or other conditions resulting from use or misuse.

Tire failure may create a risk of property damage, serious

personal injury or death.

SAFETY WARNING

Serious personal injury or death may result from a tire failure.

Many tire failures are preceded by vibration, bumps, bulges or

irregular wear. If a vibration occurs while driving your vehicle or

you notice a bump, bulge or irregular wear, have your tires and

vehicle evaluated by a qualied tire service professional.

To reduce the risk of tire failure, BRIDGESTONE strongly rec-

ommends you read and follow all safety information contained

in this manual. In addition, we recommend periodic inspec-

tion and maintenance, if necessary, by a qualied tire service

professional.

TIRE FAILURE WHILE DRIVING

SAFETY WARNING

It is not often that a properly maintained tire will “blow out”

while you are driving. More commonly, if inﬂation pressure is

lost, it will be gradual. If you do experience a blowout or sud-

den tire failure, the following information should be helpful:

• When the failure occurs, you may hear a loud noise, feel a

vibration, and/or the vehicle may pull toward the side of the

failed tire.

• DO NOT abruptly brake or turn.

• Slowly remove your foot from the accelerator, hold the steer-

ing wheel rmly, and steer to maintain your lane position.

• Once the vehicle has slowed, apply the brakes gently.

• Gradually pull over to the shoulder and come to a stop, as

far off the road as possible.

TIRE INFLATION PRESSURE

Tires need proper inﬂation pressure to operate effectively and

perform as intended. Tires carry the vehicle, passenger, and

cargo loads and transmit the braking, acceleration, and turn-

ing forces. The vehicle manufacturer recommends the inﬂation

pressures for the tires mounted on your vehicle.

SAFETY WARNING

Driving on tires with improper inﬂation pressure is dangerous.

• Under-inﬂation causes excessive tire heat build-up and

internal structural damage.

• Over-inﬂation makes it more likely for tires to be cut,

punctured, or broken by sudden impact.

These situations can cause a tire failure—(even if the tire is

properly inﬂated later)—which could lead to serious personal

injury or death. Consult the vehicle tire information placard

and/or owner’s manual for the recommended inﬂation

pressures.

In addition to tire damage, improper inﬂation pressure

may also:

• Adversely affect vehicle ride and handling.

• Reduce tire tread wear.

• Affect fuel economy.

Therefore, follow these important recommendations for tire

and vehicle safety, mileage, and economy:

• Always keep the vehicle manufacturer’s recommended

inﬂation pressure in all your tires, including the spare.

• Check their pressure monthly and before long trips or

carrying extra weight.

Your vehicle’s tire information placard and/or owner’s manual

will tell you the recommended cold inﬂation pressure for all

your tires, including the spare. Examples of placards are shown

in Figures 1 and 2. Your placard may look differently and have

different tire and loading information than that shown in either

of the gures. You must check the driver’s-side door edge

or door jamb area for the actual placard that applies to

your vehicle. For questions about locating or understanding

the tire information placard, consult your vehicle owner’s

manual or ask a qualied tire service professional.

Figure 1: EXAMPLE—Tire and Loading Information Placard

8 9

Figure 2: EXAMPLE—Tire Information Placard

Maximum Pressure Indicated on the Tire Sidewall: This is

the maximum permissible in

ﬂation pressure for the tire only.

The vehicle manufacturer’s recommended tire pressures

may be lower than, or the same as, the maximum pressure

indicated on the tire sidewall. The vehicle manufacturer’s

specication of tire pressure is limited to your particular

vehicle and takes into account your vehicle’s load, ride, and

handling characteristics, among other criteria. Since there may

be several possible vehicle applications for a given tire size, a

vehicle manufacturer may choose a different in

ﬂation pressure

specication for that same size tire on a different vehicle.

Therefore, always refer to the in

ﬂation pressure specications

on the vehicle tire information placard and/or in your vehicle

owner’s manual.

Different Tire Pressures for the Front and Rear Tires:

For some vehicles, the recommended front and rear in

ﬂation

pressures may be different (such as in the example shown in

Figure 2). Make sure you take this into account during in

ﬂation

pressure checks and when rotating tires.

Pressure Loss: Tires can lose 1 psi (7 kPa) per month under

normal conditions and can lose 1 psi (7 kPa) for every 10°F

(5.6°C) temperature drop. A puncture, leaking valve, or other

damage could also cause in

ﬂation pressure loss. If a tire loses

more than 2 psi (14 kPa) per month, have it checked by a

qualied tire service professional.

TIPS FOR SAFE TIRE INFLATION

SAFETY WARNING

ﬂating an unsecured tire is dangerous. If it bursts, it could

be hurled into the air with explosive force resulting in serious

personal injury or death. Never in

ﬂate a tire unless it is secured

to the vehicle or a tire mounting machine.

•

Check your tire pressures, including your spare tire, monthly

and before long trips or carrying extra weight. Be sure to use

an accurate pressure gauge.

•

Check inﬂation pressure when the tires are “cold.” Tires are

considered “cold” when the vehicle has been parked for

three hours or more, or if the vehicle has been driven less

than a mile (1.6 km) at moderate speed.

•

Never release pressure from a hot tire in order to reach the

recommended cold tire pressure. Normal driving causes tires

to run hotter and in

ﬂation pressure to increase. If you reduce

ﬂation pressure when your tires are hot, you may danger-

ously under-in

ﬂate your tires.

•

If it is necessary to adjust inﬂation pressure when your tires

are “hot,” set their pressure to 4 psi (28 kPa) above the

recommended cold in

ﬂation pressure. Recheck the inﬂation

pressure when the tires are cold.

•

If your tires lose more than 2 psi (14 kPa) per month, the tire,

the valve, or wheel may be damaged. Consult a qualied tire

service professional for an inspection.

•

Use valve caps to keep the valves clear of debris and to help

guard against in

ﬂation pressure loss.

TIPS FOR SAFE LOADING

SAFETY WARNING

Driving your vehicle in an overloaded condition is dangerous.

Overloading causes excessive tire heat build-up and internal

structural damage. This can cause a tire failure—(even after

the load is reduced)—which could lead to serious personal

injury or death. Consult the vehicle tire information placard,

certication label, and owner’s manual for the recommended

vehicle load limits and loading recommendations.

•

Always keep the vehicle manufacturer’s recommended

ﬂation pressure in all your tires, including the spare.

Check their pressure monthly and before long trips or

carrying extra weight.

•

Never exceed the maximum load rating stamped on the

sidewall of your tire.

•

Never exceed the gross vehicle weight rating (GVWR) or

front/rear gross axle weight ratings (GAWR) of your vehicle.

•

Consult your vehicle owner’s manual for load recommenda-

tions and special instructions (such as for trailer/towing and

snow plow installations).

TIRE DAMAGE, INSPECTION AND SERVICE LIFE

Evaluation and maintenance of your tires is important

to their performance and the service they provide to you.

Over time and/or through use, the condition of a tire can

change from exposure to everyday road conditions, the

environment, damaging events such as punctures, and

other external factors.

10 11

SAFETY WARNING

Driving on damaged tires is dangerous. A damaged tire

can suddenly fail causing serious personal injury or death.

Have your tires regularly inspected by a qualied tire

service professional.

You should visually inspect your tires on a regular basis

throughout their life, and you should have your tires

periodically evaluated by a qualied tire service professional

when your vehicle is serviced such as routine maintenance

intervals, oil changes, and tire rotations. In particular, note the

following tips for spotting tire damage:

•

After striking anything unusual in the roadway, have a quali-

ed tire service professional demount the tire and inspect it

for damage. A damaged tire may not show any visible signs

of harm. Yet, the tire may suddenly fail without warning, a

day, a week, or even months later.

•

Inspect your tires for cuts, cracks, splits or bruises in the

tread and sidewall areas. Bumps or bulges may indicate a

separation within the tire body. If you see damage or unusual

condition, have your tire inspected by a qualied tire service

professional. It may be necessary to have it removed from

the wheel for a complete inspection.

•

Inspect your tires for adequate tread depth. When the tire is

worn to the built-in indicators at 2/32 inch (1.6 mm) or less

tread groove depth, or the tire cord or fabric is exposed, the

tire is dangerously worn and must be replaced immediately.

•

Inspect your tires for uneven wear. Wear on one side of the

tread or

ﬂat spots in the tread may indicate a problem with

the tire or vehicle. Consult a qualied tire service professional.

• Inspect your wheels also. If you have a bent or cracked

wheel, it must be replaced.

•

Don’t forget to check the spare tire.

Tire Service Life

Make sure your tires, including the spare, continue to be

regularly inspected after 5 years of service to determine

if they can continue in service. Regardless of the tire’s

condition or tread depth, it is recommended that tires more

than 10 years old be taken out of service and replaced with

new tires. REMEMBER TO CHECK YOUR FULL-SIZE OR

TEMPORARY SPARE, ALSO. A spare tire over 10 years old

may look like a new tire, but it should be replaced. See “Tire

Manufacture Date,” the next section in this manual.

The 10 year period after the date of production is not an

indicator of actual service life for any individual tire. Some

tires will need to be replaced before 10 years due to condi-

tions such as punctures, impact damage, improper in

ﬂation,

overloading, tread wear or other conditions involving use

or misuse of the tire. If a tire is worn out or otherwise

unserviceable from damage or conditions of use, it should

be replaced regardless of when it was produced or placed

in service.

The vehicle manufacturer may consider vehicle performance

characteristics when making tire replacement recommendations

Consult your vehicle owner’s manual for any information

regarding tire service life and replacement and follow the

recommendations applicable to your vehicle.

TIRE MANUFACTURE DATE

The tire manufacture date is determined by examining the DOT

tire identication number, also known as the DOT serial number

or code, which can be found on at least one sidewall near the

wheel. It may be necessary to look on both sides of the tire to

nd the entire serial code. For more information on DOT serial

codes, see “Tire Sidewall Labeling” in this manual.

Tires Produced Since 2000: The last four (4) digits of the serial

code identify the week and year of production. In the example

below, the tire was produced in the 18th week of 2000. Another

example, a tire with a serial code ending in “2406” would have

been produced in the 24th week of 2006.

Tires Produced Prior to 2000: The last three (3) digits of

the serial code identify the week and year of production. For

example, a tire with a code ending in “329” would likely have

been produced in the 32nd week of 1999, but possibly produced

in 1989. If in doubt, consult a qualied tire service professional.

TIRE REPAIRS

SAFETY WARNING

Driving on an improperly repaired tire is dangerous. An

improper repair can be unreliable or permit further damage

to the tire. The tire may suddenly fail, causing serious personal

injury or death. A complete inspection and repair of your tire

in accordance with Rubber Manufacturers Association

(RMA) procedures should be conducted by a qualied tire

service professional.

While the comprehensive procedures and recommendations

for tire repair are beyond the scope of this manual, a proper tire

repair includes the following:

The tire is demounted from the wheel for a complete

inspection, inside and out. Some damage to the tire may

only be evident on the interior of the tire.

12 13

The puncture injury is 1/4 inch (6 mm)

or less and must be within the tread

area as shown in the graphic. This

helps ensure long-term tire and repair

durability.

A patch is applied to the interior of the tire

and the puncture hole is ﬁlled with a suitable plug/stem ﬁller.

This helps ensure that the interior of the tire is adequately sealed

to prevent inﬂation pressure loss and prevents contamination of

the steel belts and other plies from the elements (such as water) in

the outside world.

Additional notes about tire repairs:

• Not all punctured or damaged tires can be properly repaired;

consequently, some tires must be replaced. NEVER repair a

tire with any of the following conditions:

– Wear to the tire’s built-in treadwear indicators or to

2/32 inch (1.6 mm) remaining tread depth in any area

of the tread.

– With a puncture larger than 1/4 inch (6 mm).

– With a puncture or other damage outside the repairable

tread area (as shown in the graphic).

– With a pre-existing, improper repair.

• Any tire repair done without removing the tire from the wheel

is improper. The tire must be demounted from the wheel and

the interior inspected for damage that may not be evident on

the exterior of the tire.

• Using only a plug/stem, or using only a patch, is not a safe

or proper repair. A patch must be applied to the interior

of the tire and the puncture hole must be lled with a

suitable plug/stem ller to prevent inﬂation pressure loss and

contamination of the steel belts and other plies.

• NEVER substitute a tube for a proper repair or to remedy an

improper repair.

• Tubes, like tires, should only be repaired by a qualied tire

service professional.

• Some vehicle manufacturers do not recommend using

repaired tires. Consult your vehicle owner’s manual or

contact the vehicle manufacturer before operating a

repaired tire on your vehicle.

ASK how your tire will be repaired. ALWAYS insist on a

proper tire repair.

Emergency/Temporary Sealant or Filler Repairs: An emer-

gency/temporary sealant or ller injected into the tire, such

as by aerosol can or injection/squeeze-tube, is not a proper

repair and voids the tire Limited Warranty. A tire injected with

such sealant/ller must be replaced by a qualied tire service

professional as soon as possible.

SAFETY WARNING

Tell the tire service professional if you have used an aerosol

xer to inﬂate/seal the tire. Aerosol xers could contain a

highly volatile gas. Always remove the valve core outdoors,

away from sources of excessive heat, ﬂame, or sparks and

completely deﬂate the tire before removing it from the wheel.

Speed Rating: The tire’s speed rating is void if the tire is

repaired, retreaded, damaged, abused, or otherwise altered

from its original condition. Thereafter, it should be treated as a

non-speed rated tire. See “Tire Speed Ratings” in this manual.

Improper repair voids the tire Limited Warranty.

See “Limited Warranty” in the Warranty Details Manual under a

separate publication.

RFT (Run-Flat Technology) Tires: In addition to the above,

there are recommendations specic to the repair of RFT tires;

see “RFT Tires with Run-Flat Technology” in this manual.

TIRE MOUNTING AND OTHER SERVICING

SAFETY WARNING

Removing and replacing tires on wheels can be dangerous.

Attempting to mount tires with improper tools or procedures

may result in a tire explosion causing serious personal injury or

death. This is only a job for a qualied tire service professional.

Never perform tire service procedures without proper training,

tools, and equipment.

This manual is not intended to provide proper training

or service procedures for tire mounting, demounting,

balancing, rotation, or repair. Please leave these tasks to

qualiﬁed tire service professionals. For your safety and

that of others:

• Always stand well clear of any tire mounting operation. This

is especially important when the service operator inﬂates the

tire. If the tire has been improperly mounted, it may burst

with explosive force causing serious personal injury or death.

• Tires must match the width and diameter requirements of

the wheels. For example, 16 inch diameter tires must only be

mounted to 16 inch diameter wheels. Radial tires must only

be mounted to wheels approved for radial tires.

• Wheels must be free of cracks, dents, chips, and rust. Tires

must be free of bead damage, cuts, and punctures.

•

Never inﬂate a tire beyond 40 psi (275 kPa) to seat the

beads. Be absolutely certain beads are fully seated before

adjusting inﬂation pressure to the level recommended for

vehicle operation.

•

Never put ﬂammable substances in tire/wheel assemblies

at any time. Never put any ﬂammable substance into a tire/

wheel assembly and attempt to ignite to seat the beads.

PATCH + PLUG/STEM PATCH ONLY PLUG/STEM ONLY

14 15

•

Always stand well away from the work area when tires are

being spin balanced either on or off the vehicle.

HIGH PERFORMANCE, LOW ASPECT RATIO TIRES

Many new vehicles come equipped from the factory with high

performance and/or low aspect ratio tires. Generally, these

tires provide increased vehicle handling capability, but may

also have numerous engineering performance trade-offs

associated with their designs.

•

Low aspect ratio tires, with reduced sidewall height, may be

more susceptible to damage from potholes, road hazards,

and other objects such as curbs. This is true for the wheels

as well. Therefore, as with all other tires, it is important to

drive with care and maintain proper in

ﬂation pressure and

load conditions. See “Tire In

ﬂation Pressure” and “Tire

Damage, Inspection and Service Life” in this manual.

•

Some sports cars and other vehicles with enhanced han-

dling performance, including sedans and light trucks/SUVs,

may be originally equipped with high performance tires that

are more optimized for warmer weather use. Colder, winter

weather traction may be reduced for these types of tires.

Winter tires may be recommended by the vehicle manufac-

turer for colder weather application. See “Winter Tires,” the

next section in this manual.

•

High performance tires may also wear more quickly, ride

more rmly, and produce more noise during operation.

Consult your vehicle owner’s manual and tire information

placard, or a qualied tire service professional, for more

information and specics regarding these types of tires.

WINTER TIRES

SAFETY WARNING

Winter driving presents special challenges for vehicle mobility.

The use of winter tires (including studs and chains)—while

improving traction performance in snow and ice—requires

special care with regard to acceleration, braking, cornering,

and speed. It is important to drive with care, not only on snow

and ice, but on dry and wet roads as well.

In winter driving conditions, vehicle control and safe operation

under braking and cornering is especially dependent upon

the rear tires. For this reason, winter tires are best applied to

all wheel positions. Some vehicles have specic recommen-

dations regarding winter tire use; consult your vehicle owner’s

manual and tire information placard.

•

If winter tires are to be applied to the front axle of any

vehicle, they must also be applied to the rear axle for safe

operation. This applies to all passenger cars and light trucks,

including front wheel drive, 4x4, and all-wheel-drive vehicles.

•

If winter tires are to be applied to the rear axle of any

vehicle, it is recommended that they also be installed on

the front axle.

•

It is generally acceptable to apply a tire with a lower speed

rating than your original tires for use in winter weather

conditions; however, speed should be reduced accordingly.

All winter tires should be the same speed rating. See “Tire

Speed Ratings” in this manual.

•

Winter tires used in warm weather conditions may wear

more rapidly.

•

Studded winter tires follow the same recommendations as

above; consult a qualied tire service professional for infor-

mation regarding any seasonal restrictions.

HIGH SPEED DRIVING

SAFETY WARNING

Driving at high speed is dangerous and can cause an

accident, resulting in serious personal injury or death.

•

Regardless of the speed and handling capabilities of

your car and its tires, a loss of vehicle control can result

from exceeding the maximum speed allowed by law or

warranted by trafc, weather, vehicle, or road conditions.

•

High-speed driving should be left to trained professionals

operating under controlled conditions.

•

No tire, regardless of its design or speed rating, has unlimit-

ed capacity for speed, and a sudden tire failure can occur if

its limits are exceeded. See “Tire Speed Ratings,” the next

section in this manual.

Refer to your vehicle owner’s manual for any tire pressure

recommendations for high speed driving.

TIRE SPEED RATINGS

A tire bearing a letter “speed rating” designation indicates the

tire’s speed capability according to standardized laboratory

tests. This speed rating system is intended to permit compar-

ison of the speed capabilities of different tires. When replac-

ing your tires, consult your vehicle owner’s manual and tire

information placard for recommendations, if any, concerning

the use of speed rated tires.

•

To avoid reducing the speed capability of the vehicle, replace

a speed rated tire only with another tire having at least the

same speed rating. It is the “top speed” of the “slowest” tire

on the vehicle which limits the vehicle’s top speed without

tire failure.

16 17

• The tire’s speed rating is void if the tire is repaired, retread-

ed, damaged, abused, or otherwise altered from its original

condition. Thereafter, it should be treated as a non-speed

rated tire.

• Non-speed rated tires are usually for ordinary passenger car

or light truck service and not for high speed driving.

• For winter tires used in cold weather conditions, it is gen-

erally acceptable to apply a tire with a lower speed rating

than your original tires; however, speed should be reduced

accordingly. All winter tires should be the same speed rating.

Some vehicles have specic recommendations regarding

winter tire use; consult your vehicle owner’s manual and tire

information placard. See “Winter Tires” in this manual.

These speed ratings are based on standardized laboratory

tests under specic, controlled conditions. While these tests

may relate to performance on the road, real-world driving is

rarely identical to any test conditions. Your tire’s actual speed

capability may be less than its rated speed since it is affect-

ed by factors such as inﬂation pressure, load, tire condition

(including damage), wear, vehicle condition (including align-

ment), driving conditions, and duration at which the speed is

sustained. Use the following chart to compare the speed rat-

ings of tires. Remember: regardless of the tire’s speed rating,

drivers should obey speed limits and adjust their speed based

on trafc, weather, vehicle and road conditions.

The tire’s speed rating designation appears on the tire

side-wall with the tire size. Examples:

P275/40ZR17 max > 149 mph (240 km/h) ****

P275/40R17 93W max = 168 mph (270 km/h)

P275/40ZR17 93W max = 168 mph (270 km/h)

P275/40ZR17 93Y max = 186 mph (300 km/h)

P275/40ZR17 93(Y) max > 186 mph (300 km/h) ****

* In standardized laboratory tests that relate to highway

speeds. Actual tire speed and performance capability

depend on factors such as inﬂation pressure, load, tire

condition, wear, and driving conditions.

** Any tire having a maximum speed capability above 149 mph

(240 km/h) may, at the tire manufacturer’s discretion, include

a “Z” in the size designation (i.e. P275/40ZR17).

*** For tires having a maximum speed capability above 186

mph (300 km/h), a “Z” must appear in the size designation

and a “Y” marked in brackets (as shown) in the service

description.

**** Consult the tire manufacturer for maximum speed

capability.

TIRE SPINNING

SAFETY WARNING

Spinning a tire to extract a vehicle stuck in mud, ice, snow, or

wet grass can be dangerous. A tire spinning at a speedometer

reading above 35 mph (55 km/h) can in a matter of seconds

reach a rotation speed capable of disintegrating a tire with

explosive force. Under some conditions, a tire may be spin-

ning at a speed twice that shown on the speedometer. This

could cause serious personal injury or death to a bystander or

passenger. Never spin a tire above a speedometer reading of

35 mph (55 km/h).

RADIAL TIRE ROTATION

The purpose of tire rotation is to minimize irregular or uneven

wear caused by maintaining a tire in one rotation direction and

one position over an extended period. Rotate tires as rec-

ommended by the vehicle manufacturer or every 5,000 miles

(8,000 km). Individual tire pressures must be checked after

rotation and adjusted to the vehicle manufacturer’s recom-

mendation for the tire’s new location on the vehicle. Vehicle

alignment should be checked if irregular wear is evident.

For vehicles with a “temporary use” spare tire, follow the

vehicle manufacturer’s recommended pattern for rotation,

or, if not provided, the following may be used:

If your spare is the same size, load rating, and type of tire

as your road tires, it should be included in the tire rotation

process. For vehicles with a “full-size” spare, the following

rotation patterns may be used:

Speed

Note:

• Never include a “temporary use” spare tire in the rotation.

• Tires with directional tread patterns must be rotated so the

direction of revolution does not change; this may require

demounting/mounting the tires.

• Special attention should be given if your vehicle is equipped

with a Tire Pressure Monitoring System (TPMS). Rotation of

your tires may affect the system; consult your vehicle own-

er’s manual or a qualied tire service professional.

• Some vehicles may have different size tires/wheels on front

and rear which would restrict rotation. Always check and

follow the vehicle manufacturer’s rotation recommendation.

• To use a full-size spare in the rotation pattern on vehicles

with dual rear wheels, consult your vehicle owner’s manual

for the recommend

ed procedures or consult the vehicle

manufacturer.

TIRE REPLACEMENT AND TIRE MIXING

SAFETY WARNING

Driving your vehicle with an improper mix of tires is danger-

ous. Your vehicle’s handling characteristics may be seriously

affected. You could have an accident resulting in serious per-

sonal injury or death. Consult your vehicle owner’s manual, tire

information placard, and a qualied tire service professional

for proper tire replacement.

Unless otherwise specied by the vehicle manufacturer, it is

recommended that all road tires be the same size, type, and

speed rating. Never mix different size tires on an axle, except

for temporary use of a spare (see “Your Spare Tire,” the next

section in this manual).

When it is necessary to replace one or more tires, consider

that applying new tires in pairs on an axle, or to all wheel

positions, helps to optimize vehicle performance and avoid

malfunction of mechanical or electronic vehicle systems (i.e.

drive-train/transmission, anti-lock brakes, traction control).

Replacing Fewer Than Four Tires: Whether your vehicle is

front-, rear-, or all-wheel drive, if your rear tires lose traction

because of hydroplaning on a wet road, an oversteer skidding

condition may result and lead to loss of control, particularly in

a turn. Generally, new tires provide increased resistance to hy-

droplaning due to their full tread depth. With the new tires on

the rear, the oversteer skidding condition may be more easily

avoided. Therefore, if replacing only one or two tires at a time:

• Two new tires should be placed on the rear axle.

• One new tire should be paired with another tire from the

vehicle with the deepest tread depth, and then both should

be placed on the rear axle.

Winter Tires: See “Winter Tires” in this manual.

Speed Rating: See “Tire Speed Ratings” in this manual.

ll Wheel Drive or Four-Wheel Drive: Some vehicle manufac-

turers have specic recommendations related to the replace-

ment of tires on All Wheel Drive or Four-Wheel Drive vehicles.

This may include the recommendation to replace more than

one tire or, in some cases, up to all four tires. Please consult

your vehicle owner’s manual or consult your vehicle manufac-

turer for additional information.

Additional or alternate recommendations may apply for some

vehicles. Always refer to and follow the vehicle manufacturer’s

tire replacement and tire application recommendations; con-

sult your vehicle owner’s manual and tire information placard.

YOUR SPARE TIRE

Consult your vehicle owner’s manual for proper application of

your spare tire. Your car may be equipped with a “temporary

use” spare tire; this spare may differ in size and construction

from the other tires on your vehicle.

SAFETY WARNING

Check inﬂation pressure before use. Failure to have proper

inﬂation pressure when using your spare tire can result in

serious personal injury or death. See “Tire Inﬂation Pressure”

in this manual.

SAFETY WARNING

Mounting a “temporary use” tire on a wheel which is not

specically designed for it, or placing another type tire on a

wheel designated for temporary use can be dangerous. Your

vehicle’s handling characteristics can be seriously affected.

You could have an accident resulting in serious personal injury

or death. Consult your vehicle owner’s manual for proper

application of your “temporary use” spare tire.

The spare tire in your vehicle is intended to be used as a spare

when needed. The spare tire carrier is not intended to be used

for long term storage, except for “temporary use” tires. If your

spare is the same size, load rating, and type of tire as your

road tires, it should be included in the tire rotation process;

see “Radial Tire Rotation” in this manual.

The spare should be included in regular tire inspections and

inﬂation pressure checks. In addition, your spare should be

replaced 10 years after date of manufacture, regardless of

condition or tread depth. For more information, see “Tire

Damage, Inspection and Service Life” in this manual.

20 21

TIRE STORAGE

Tires should be stored indoors in a cool, dry place. Water

should not be allowed to collect inside them. Tires should

be placed away from electric generators/motors and sources

of heat such as hot pipes. Storage surfaces should be clean

and free of grease, gasoline or other substances which can

deteriorate the rubber.

SAFETY WARNING

Improper storage can damage your tires in ways that may not

be visible and can lead to a failure resulting in serious personal

injury or death.

The spare tire in your vehicle is intended to be used as a

|spare when needed. The spare tire carrier is not intended to

be used for long term storage, except for “temporary use”

tires. For more information, see “Your Spare Tire” and

“Radial Tire Rotation” in this manual.

TIRE REGISTRATION

Registration of your tires is an important safety precaution

since it enables the manufacturer to notify you in the event

of a recall. When you purchase replacement tires, the retailer

will provide a registration card on which the tire identication

numbers have been recorded; ll in your name and address

on the card and mail it promptly. Some retailers may submit

the registration for you. You do not need to register tires which

come as original equipment on new vehicles—the vehicle and

tire manufacturers handle that for you.

If your vehicle is equipped with Bridgestone or Firestone brand

RFT tires, this chapter presents specic maintenance and

safety issues associated with these tires that are in addition

to those covered elsewhere in this manual.

What is RFT? Run-Flat Technology tires are extraordinary

tires that utilize specially designed components to temporarily

support your vehicle in the event of inﬂation pressure loss,

such as from a puncture. This gives you the ability to

drive to a convenient and safe location to change your tire

(if equipped with a spare) or have it inspected for possible

repair or replacement.

Naturally, certain run-ﬂat and low pressure operating

limitations apply, which vary according to the specic

self-supporting tire design. Like all tires, during normal

operation, they must be properly inﬂated and maintained.

Regardless of the design or quality, no tire is indestructible.

RFT—How to Identify: Bridgestone and Firestone brand tires

are marked on the sidewalls, near the wheel, with the RFT

logo (shown above).

RFT INFLATION PRESSURE

Like other tires, RFT tires need proper inﬂation pressure main-

tenance for safe operation and to achieve the maximum tire

life and performance. Check inﬂation pressures monthly and

before long trips or carrying extra weight. Use an accurate tire

gauge and check pressures when the tires are cold. Follow the

vehicle manufacturer’s recommendation for inﬂation pressure

settings as indicated on the vehicle tire information placard

and/or in the vehicle owner’s manual. Do not forget the spare,

if applicable. See “Tire Inﬂation Pressure” in this manual.

TIRE PRESSURE MONITORING SYSTEM (TPMS)

A functioning tire pressure monitoring system (TPMS) must be

used with your RFT tires. Because these tires ride so well even

without inﬂation pressure, the TPMS may be necessary to

alert you of an inﬂation pressure loss condition. When alerted,

follow the instructions in your vehicle owner’s manual and see

“Run-Flat or Low Tire Pressure Operation,” the next section in

this manual.

The vehicle or TPMS manufacturer may advise checking the

TPMS regularly to conrm it is in working order. In addition,

a new pressure sensor, certain components, or reprogramming

may be necessary when a tire is serviced. Consult your

vehicle owner’s manual, vehicle manufacturer, or authorized

RUN-FLAT or LOW TIRE PRESSURE OPERATION

SAFETY WARNING

Serious personal injury or death may result from a tire failure

or accident due to improper run-

ﬂat or low tire pressure

operation. Read and follow the instructions below, and the

other maintenance and safety recommendations elsewhere

in this manual.

General Instructions

The Tire Pressure Monitoring System (TPMS) required in your

vehicle may have different methods of alerting you when your

tire has lost in

ﬂation pressure. Consult your vehicle owner’s

manual for the details of your TPMS. Once the TPMS has

indicated that a tire has reduced in

ﬂation pressure, the

run-

ﬂat mode of operation has commenced. During this

phase of operation, please follow these instructions:

•

Reduce speed as much as safely and reasonably pos-

sible; do not exceed 50 mph (80 km/h). The greater the

speed, the less distance the tire can travel.

•

Avoid abrupt or aggressive acceleration, braking, or

cornering maneuvers as much as safely and reasonably

possible. Pot holes and other road hazards should be avoid-

ed. Careful driving limits potential damage to the tire, wheel,

and vehicle.

•

Proceed to a safe and convenient location for tire ser-

vice as soon as possible. Take note of your odometer; your

operation distance is limited. See “Distance—How Far You

Can Drive,” the next section in this manual.

•

If an unusual vibration or vehicle handling difﬁculty

arises, stop driving as soon as safely and reasonably

possible. The tire may be about to suddenly fail. Release the

accelerator and gradually reduce speed. The tire must be

replaced before proceeding.

•

If towing a trailer, stop driving as soon as safely and

reasonably possible. In this condition, it is potentially

dangerous to operate a vehicle/trailer combination. If

possible, disconnect the trailer and proceed as noted

above. Do not continue to tow any trailer until proper tire

service or replacement has been performed.

•

Do not touch a tire recently run-low or run-ﬂat (it may

be very hot). Allow the tire to cool before handling.

DISTANCE—HOW FAR YOU CAN DRIVE

RFT tires are capable of operating up to the distance of 50

miles (80km) at a maximum speed of 50 mph (80 km/h) in

run-

ﬂat or low pressure operation. However, the distance

capability may be less (or more) depending upon the actual

vehicle application and specic operating conditions.

Factors affecting run-

ﬂat or low tire pressure operating

distance include vehicle speed, load, and maneuvering;

the amount of in

ﬂation pressure loss; the extent of any tire

damage; and ambient temperature. To maximize the distance

capability in a run-

ﬂat or low pressure condition:

•

Reduce vehicle speed as much as safely and reasonably

possible. Do not exceed 50 mph (80 km/h).

•

Avoid abrupt or aggressive acceleration, braking, or corner-

ing maneuvers as much as safely and reasonably possible.

Avoid pot holes and other road hazards.

Higher vehicle loads (such as with more passengers or cargo)

and higher ambient temperatures decrease the distance

capability of an RFT tire in run-

ﬂat or low pressure operation.

Note:

•

If the sidewall of the RFT tire species a run-ﬂat or low pres-

sure distance limitation, do not exceed the specied distance.

• The distance capability of the vehicle is limited to the

distance capability of the specic RFT tire that is operating

in a run-

ﬂat or low pressure condition.

•

For original equipment specication RTF tires applied to

vehicles originally equipped with these tires, see the vehicle

owner’s manual for distance limitations during run-

ﬂat or low

pressure operation.

If in doubt about the distance capability of an RFT tire, do not

exceed 50 miles (80 km) in run-low or low pressure operation.

Seek tire service as soon as possible to minimize tire damage.

SPECIAL SERVICE and REPAIR ISSUES

Authorized Bridgestone or Firestone Retail Locations

Because of the advanced technology and design of RFT tires

and the required tire pressure monitoring systems (TPMS),

only qualied tire service professionals with the proper equip-

ment and training should service RFT tires. For instance, the

use of tire mounting equipment that is unsuitable for an RFT

tire may damage the tire beyond repair. Therefore, it is recom-

mended to go to an authorized Bridgestone or

Firestone brand tire retailer for service and replacement.

Visit Bridgestonetire.com to locate the nearest Bridgestone or

Firestone brand retailer.

24 25

Inspection after Run-Flat or Low Pressure Operation

Following run-ﬂat or low tire pressure operation, or in the

event of any other tire damage or unusual condition, it is very

important to obtain a proper and complete tire evaluation as

soon as possible.

Rotation

Follow the vehicle manufacturer’s recommendations, or rotate

every 5,000 miles (8,000 km) per the recommendations in this

manual (see “Radial Tire Rotation”). In some cases, TPMS

devices require reprogramming with each tire rotation.

RFT Tire Replacement

Do not replace or mix RFT tires with conventional tires, unless

on an emergency/temporary basis. Conventional tires do not

have run-ﬂat capability and the handling characteristics of the

vehicle with these tires may be different. If a conventional tire

is used on an emergency/temporary basis, verify that its size,

load capacity, inﬂation pressure, and speed rating speci-

cations meet the requirements of the vehicle. Replace any

conventional tire with the proper RFT tire as soon as possible.

RFT Tire Damage and Repair

No tire, regardless of its design or quality is indestructible. RFT

tires can be ultimately rendered unusable due to a puncture or

other road hazard as well as from improper low tire pressure

operation. Some punctures may be repaired under certain

restrictions and prescribed procedures. An improper repair is

unsafe and will void the Limited Warranty.

When driven ﬂat or with low pressure, factors affecting rep-

arability include vehicle speed, load, and maneuvering; the

amount of inﬂation pressure loss; and ambient temperature. In

any situation, the extent and location of direct damage from a

puncturing object or other road hazard are also critical factors.

RFT tires are not repairable in any of the following situations:

• If the tire was operated with inﬂation pressure less than 15

psi (100 kPa).

• Abrasion or other damage is present on the exterior tread,

sidewall or bead areas.

• Abrasion, wrinkling, or separation is present on the tire

interior.

• Any condition or damage is present that disqualies repair of

a conventional tire.

A qualied tire service professional should fully inspect your

tire, inside and out, to determine if the tire can be repaired.

Tire damage is not always visible from the outside and the tire

must be removed from the wheel for a complete inspection.

For more information, see “Tire Repairs” in this manual.

Note: Some vehicle manufacturers do not recommend using

repaired tires. Such recommendations apply to RFT tires. Use

of RFT tires deemed non-reparable may result in damage to

vehicle, injury, or death. Consult your vehicle owner’s man-

ual or contact the vehicle manufacturer before operating a

repaired tire on your vehicle.

REFERENCE INFORMATION

TIRE SIDEWALL LABELING

A lot can be learned by reading the tire’s sidewall. The

following gures show typical information on the sidewall

of passenger (Figure 3) and light truck tires (Figure 4):

Figure 3: Typical Passenger Tire Markings

Figure 4: Typical Light Truck Tire Markings

26 27

Tire Size, Load Range, Load Index, and Speed Symbol:

DOT Symbol and Tire Identiﬁcation Number: “DOT” symbol

constitutes a certication that the tire conforms to applica-

ble U.S. Department of Transportation motor vehicle safety

standards (for tires). Following the “DOT” symbol is the tire

identication number, also known as the DOT serial number or

code. The DOT TIN is commonly known as the “DOT number”

and is marked in full on at least one sidewall near the bead.

Please refer to the infographic below.

The DOT symbol and tire identication number can be found

on at least one sidewall near the wheel. The other sidewall

may have a partial serial code that excludes (e) and (f) above.

Maximum Load and Inﬂation: The maximum load and max-

imum inﬂation pressure is marked on each sidewall in metric

and English units. For example:

MAX LOAD 685 kg (1510 lbs) AT 240 kPa (35 psi) MAX PRESS

Note:

The load and inﬂation values marked on the tire side-

wall are maximum permissible values for the tire only. Never

assume that these values are the actual recommended load

capacity or tire pressure values for your vehicle. See “Tire

Inﬂation Pressure,” “Tips for Safe Tire Inﬂation,” and “Tips for

Safe Loading” in this manual.

Ply Composition and Materials: The actual number of plies in

the sidewall and tread area and the generic name(s) of their cord

material(s) are marked on at least one side-wall. For example:

TREAD 2 PLY POLYESTER + 2 STEEL

SIDEWALL 2 PLY POLYESTER

Radial: Radial ply tires will have the word “radial” on at least

one sidewall. An “R” in the tire size designation also indicates

radial ply construction.

Tubeless or Tube Type: Tires are marked as either “tube-less”

or “tube type,” whichever is applicable, on at least one sidewall.

UNIFORM TIRE QUALITY GRADING

The Uniform Tire Quality Grading (“UTQG”) standards are

intended to assist you in making an informed choice in your

purchase of passenger car tires by providing information indi-

cating relative performance of these tires in the areas of tread

wear, wet braking traction (straight-ahead), and temperature

resistance. All passenger car tires must conform to federal

safety requirements in addition to these grades.

Treadwear

The treadwear grade is a comparative rating based on the

wear rate of the tire when tested under controlled condi-tions

on a specied government test course. For example, a tire

graded 150 would wear one and one half (1½ ) times as well

on the government course as a tire graded 100. The relative

performance of tires depends upon the actual conditions of

their use, however, and may depart signicantly from the norm

due to variation in driving habits, service practices and differ-

ences in road characteristics and climate.

Traction

The traction grades, from highest to lowest, are AA, A, B,

and C. Those grades represent the tire’s ability to stop on

wet pavement as measured under controlled conditions on

specied government test surfaces of asphalt and concrete.

Warning: The traction grade assigned to a tire is based

on straight-ahead braking traction tests, and does not

include acceleration, cornering, hydroplaning, or peak

traction characteristics.

Temperature

The temperature grades are A (the highest), B, and C, repre-

senting the tire’s resistance to the generation of heat and its

ability to dissipate heat when tested under con-trolled condi-

tions on a specied indoor laboratory test wheel. Sustained

high temperature can cause the material of the tire to degen-

erate and reduce tire life, and excessive temperature can lead

to sudden tire failure. The grade C corresponds to a level of

performance which all passenger car tires must meet under

the Federal Motor Vehicle Safety Standard No.109. Grades B

and A represent higher levels of performance on the labora-

tory test wheel than the mini-mum required by law. Warning:

The temperature grade is established for a tire that is properly

inﬂated and not overloaded. Excessive speed, underinﬂation,

or excessive loading, either separately or in combination, can

cause heat buildup and a possible tire failure.
