It is impossible to predict when tires should be replaced based on their calendar age
alone. However the older a tire the greater the chance that it will need to be replaced due
to the service-related evolution or other conditions found upon inspection or detected
during use.
While most tires will need replacement before they achieve 10 years, it is recommended
t h
at any tires in service 10 years or more from the date of manufacture, including spare
tires, be replaced with new tires as a simple precaution even if such tires appear
serviceable and even if they have not reached the legal wear limit.
For tires that were on an original equipment vehicle i.e., acquired by the consumer on a
n e
w vehicle, follow the vehicle manufacturer’s tire replacement recommendations, when
specified (but not to exceed 10 years).
The date when a tire was manufactured is located on the sidewall of each tire.
C o
nsumers should locate the Department of Transportation (DOT) code on the tire which
begins with DOT and ends with the week and year of manufacture. For example, a DOT
code ending with "2204" indicates a tire made in the 22nd week (May) of 2004.

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.
To reduce the risk of tire failure, Bridgestone® Firestone® North American Tire, LLC
s t
rongly recommends you read and follow all safety information contained in this
manual. In addition, we recommend periodic inspection and maintenance, if necessary,
by a qualified tire service professional.
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 qualified tire service professional.

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 different and have
different tire and loading information than that shown in either of the figures. You must
check the driver 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 qualified tire service professional.
Figure 1: EXAMPLE—Tire And Loading Information Placard
Figure 2: EXAMPLE—Tire Information Placard
Maximum Pressure Indicated on the Tire Sidewall: This is the maximum permissible
inflation 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 specification 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 inflation
pressure specification for that same size tire on a different vehicle. Therefore, always
refer to the inflation pressure specifications on the vehicle tire information placard and/
or in your vehicle Owner’s Manual.
Different Tire Pressures for the Front and Rear Tires: F
or some vehicles, the
recommended front and rear inflation pressures may be different (such as in the
example shown in Figure 2). Make sure you take this into account during inflation
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 inflation pressure loss. If a tire loses more than 2 psi
(14 kPa) per month, have it checked by a qualified tire service professional.
TIPS FOR SAFE TIRE INFLATION
• 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.
• C heck inflation pressure when the tires are “cold.” Tires are considered “cold” when
t
he vehicle has been parked for three hours or more, or if the vehicle has been driven
less than a mile at moderate speed.
• N ever release pressure from a hot tire in order to reach the recommended cold tire
p
ressure. Normal driving causes tires to run hotter and inflation pressure to increase.
If you reduce inflation pressure when your tires are hot, you may dangerously under -
inflate your tires.
• I f it is necessary to adjust inflation pressure when your tires are “hot”, set their pres -
s
ure to 4 psi (28 kPa) above the recommended cold inflation pressure. Recheck the
i n
flation pressure when the tires are cold.
• I f your tires lose more than 2 psi (14 kPa) per month, the tire, the valve, or wheel may
b
e damaged. Consult a qualified tire service professional for an inspection.
• U se valve caps to keep the valves clear of debris and to help guard against inflation
p
ressure loss.
TIPS FOR SAFE LOADING
• 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.
• N ever exceed the maximum load rating stamped on the sidewall of your tire.
WARNING!
Inflating 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 inflate a tire unless
it is secured to the vehicle or a tire mounting machine.
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 at a later date, which could lead to serious personal injury or death.
Consult the vehicle tire information placard, certification label, and owner’s manual
for the recommended vehicle load limits and loading recommendations.

• Never exceed the Gross Vehicle Weight Rating (GVWR) or front/rear Gross Axle Weight Rating (GAWR) of your vehicle.
• C onsult your vehicle Owner’s Manual for load recommendations and special instruc -
t
ions 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.
You should visually inspect your tires on a regular basis throughout their life, and you
sh
ould have your tires periodically evaluated by a qualified 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:
• A fter striking anything unusual in the roadway, have a qualified tire service profes -
s
ional demount the tire and inspect it for damage. A tire may not have visible signs of
d a
mage on the tire surface. Yet, the tire may suddenly fail without warning, a day, a
week, or even months later.
• I nspect your tires for cuts, cracks, splits or bruises in the tread and sidewall areas.
B
umps or bulges may indicate a separation within the tire body. Have your tire
inspected by a qualified tire service professional. It may be necessary to have it
removed from the wheel for a complete inspection.
• I nspect your tires for adequate tread depth. When the tire is worn to the built-in indi -
c
ators at 2/32 of an inch (1.6 mm) or less tread groove depth, or the tire cord or fabric
i s
exposed, the tire is dangerously worn and must be replaced immediately.
• I nspect your tires for uneven wear. Wear on one side of the tread or flat spots in the
t
read may indicate a problem with the tire or vehicle. Consult a qualified tire service
professional.
• I nspect your wheels also. If you have a bent or cracked wheel, it must be replaced.
•
Don’t forget to check the spare tire.
M
ake sure your tires, including the spare tire, continue to be regularly inspected after 5
y e
ars of service to determine if they can continue in service. Even when your tires appear
to be usable from their external appearance or the tread depth may have not reached
the minimum wear out depth, it is recommended that all tires (including spare tires and
“temporary use” spares) more than 10 years old be replaced with new tires.
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 qualified tire
service professional.

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
conditions such as punctures, impact damage, improper inflation, 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
ma
king 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 identification
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 find
the entire serial code. For more information on DOT serial codes, see “Tire Sidewall
Labeling” in this manual.
Tires Produced Since 2000: T
he 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: T
he 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 qualified tire service professional.
TIRE REPAIRS
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 US Tire Manufacturers
Association (USTMA) procedures should be conducted by a qualified 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.
• The puncture injury is 1/4 of an inch (6 m
m) 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 suit -
a
ble plug/stem filler. T
his 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:
• N ot all punctured or damaged tires can be properly repaired; consequently, they must
b
e replaced. NEVER repair a tire with any of the following conditions:
• W ear to the tire’s built-in tread wear indicators or to 2/32 of an inch (1.6
mm)
re
maining tread depth in any area of the tread.
• W ith a puncture larger than 1/4 of an inch (6
mm).
• W ith a puncture or other damage outside the repairable tread area (as shown in
t
he graphic).
• W ith a pre-existing, improper repair.
•
A ny tire repair done without removing the tire from the wheel is improper. The tire must
b
e 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 filled with a
suitable plug/stem filler to prevent inflation pressure loss and contamination of the
steel belts and other plies.
• N EVER substitute a tube for a proper repair or to remedy an improper repair.
•
Tubes, like tires, should only be repaired by a qualified tire service professional.
•
Some vehicle manufacturers do not recommend using repaired tires. Consult your
v
ehicle 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: A
n emergency/temporary sealant or
filler 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/filler
must be replaced by a qualified tire service professional as soon as possible.
Speed Rating: T
he 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. S
ee “Limited Warranty” in this manual.
RFT (Run-Flat Technology) Tires: I
n addition to the above, there are recommendations
specific to the repair of RFT tires; see “RFT Tires with Run-Flat Technology” in this
manual.
TIRE MOUNTING AND OTHER SERVICING
WARNING!
Tell the tire service professional if you have used an aerosol fixer to inflate/seal the
tire. Aerosol fixers 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.
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 qualified 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:
• A lways stand well clear of any tire mounting operation. This is especially important
w
hen 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.
• T ires must match the width and diameter requirements of the wheels. For example,
1
6 inch diameter tires must only be mounted to 16 inch diameter wheels. Radial tires
m u
st only be mounted to wheels approved for radial tires.
• W heels must be free of cracks, dents, chips, and rust. Tires must be free of bead
d
amage, cuts, and punctures.
• N ever inflate a tire beyond 40 psi (275 kPa) to seat the beads. Be absolutely certain
b
eads are fully seated before adjusting inflation pressure to the level recommended
for vehicle operation.
• N ever put flammable substances in tire/wheel assemblies at any time. Never put any
f
lammable substance into a tire/wheel assembly and attempt to ignite to seat the
beads.
• A lways stand well away from the work area when tires are being spin balanced either
o
n 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.
• Lo w aspect ratio tires, with reduced sidewall height, may be more susceptible to
d
amage 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 inflation pressure and load conditions. See “Tire Inflation Pres -
sure” and “Tire Damage, Inspection and Service Life” in this manual.
• Some sports cars and other handling performance enhanced vehicles, including s
edans 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
manufacturer for colder weather application. See “Winter Tires,” the next section in
this manual.
• H igh performance tires may also wear more quickly, ride more firmly, and produce
m
ore noise during operation.
Consult your vehicle Owner’s Manual and tire information placard, or a qualified tire
s e
rvice professional, for more information and specifics regarding these types of tires.
