REPLACEMENT OF TWO TIRES
It is recommended that all four tires are replaced at the same time. However, whenever
on

ly two tires are replaced, the new ones should be put on the rear. The new tires, with
deeper tread, may provide better grip and water evacuation in wet driving conditions.
CUSTOMIZATION OF TIRES, WHEELS, OR SUSPENSION ON SUVS AND LIGHT
TRUCKS
Due to their size, weight and higher center of gravity, vehicles such as SUVs and light
trucks do not
have the same handling characteristics as automobiles. Because of these
differing characteristics, failure to operate your SUV/truck in a proper and safe manner
can increase the likelihood of vehicle rollover. Modifications to your SUV/truck tire size,
tire type, wheels or suspension can change its handling characteristics and further
increase the likelihood of vehicle rollover. Whether your SUV/truck has the original
equipment configuration for tires, wheels and suspension or whether any of these items
have been modified, always drive safely, avoid sudden, sharp turns or lane changes and
obey all traffic laws. Failure to do so may result in loss of vehicle control leading to an
accident and serious injury or death.
TIRE ALTERATIONS
Do not make or allow to be made any alterations on your tires. Alterations may prevent
p r

oper performance, leading to tire damage which can result in an accident. Tires which
become unserviceable due to alterations such as trueing, whitewall inlays, addition of
balancing or sealant liquids, or the use of tire dressing containing petroleum distillates
are excluded from warranty coverage.
REPAIRS - WHEREVER POSSIBLE, SEE YOUR BFGOODRICH® TIRE RETAILER AT ONCE
If any BFGoodrich® tire sustains a puncture, have the tire demounted and thoroughly
i n

spected by any BFGoodrich® tire retailer for possible damage that may have occurred.
A tread area puncture in any BFGoodrich® passenger or light truck tire can be repaired
p r

ovided that the puncture hole is not more than 1/4 of an inch in diameter, not more
than one radial cable per casing ply is damaged, and the tire has not been damaged
further by the puncturing object or by running underinflated. Tire punctures consistent
with these guidelines can be repaired by following the Rubber Manufacturers Association
(RMA) recommended repair procedures.
TIRE REPAIRS
Repairs of all tires must be of the combined plug and inside patch type. Plug only repairs
are improper. A tire should be removed from the rim and inspected prior to repair. Any
tire repair done without removing the tire from the rim is improper. An improperly
repaired tire will cause further damage to the tire by either leaking air or allowing air,
moisture and contaminants to enter the structure of the tire. An improperly repaired tire
can fail suddenly at a later date.
Never repair a tire with less than 2/32 of an inch tread remaining. At this tread depth,
t h

e tire is worn out and must be replaced.

FOLLOW THESE MOUNTING RECOMMENDATIONS
Tire changing can be dangerous and must be done by professionally trained persons
us

ing proper tools and procedures as specified by the Rubber Manufacturers
Association (RMA).
Your tires should be mounted on wheels of correct size and type and which are in good,
c le

an condition. Wheels that are bent, chipped, rusted (steel wheels) or corroded (alloy
wheels) may cause tire damage. The inside of the tire must be free from foreign material.
Have your retailer check the wheels before mounting new tires. Mismatched tires and
rims can explode during mounting. Also, mismatched tires and rims can result in
dangerous tire failure on the road. If a tire is mounted by error on the wrong-sized rim, do
not remount it on the proper rim — scrap it. It may have been damaged internally (which
is not externally visible) by having been dangerously stretched and could fail on the
highway.
Old valves may leak. When new tubeless tires are mounted, have new valves of the
c o

rrect type installed. Tubeless tires must only be mounted on wheels designed for
tubeless tires i.e., wheels which have safety humps or ledges.
It is recommended that you have your tires and wheels balanced. Tires and wheels which
a r

e not balanced may cause steering difficulties, a bumpy ride, and irregular tire wear.
Be sure that all your valves have suitable valve caps. The valve cap is the primary seal
a g

ainst air loss.
SERVICE LIFE FOR PASSENGER CAR AND LIGHT TRUCK TIRES INCLUDING SPARE
TIRES
The following recommendation applies to passenger car and light truck tires. Tires are
composed of various types of material and rubber compounds, having performance
properties essential to the proper functioning of the tire itself. These component
properties evolve over time. For each tire, this evolution depends upon many factors
such as weather, storage conditions, and conditions of use including load, speed,
inflation pressure, maintenance etc. to which the tire is subjected throughout its life. This
service-related evolution varies widely so that accurately predicting the serviceable life
of any specific tire in advance is not possible.
In addition to regular inspections and inflation pressure maintenance by consumers, it is
re

commended to have passenger car and light truck tires, including spare tires,
inspected regularly by a qualified tire specialist, such as a tire dealer, who will assess the
tire’s suitability for continued service. Tires which have been in use for five years or more
should continue to be inspected by a specialist at least annually.
Consumers are strongly encouraged to be aware not only of their tires’ visual condition
an
d inflation pressure but also of any change in dynamic performance such as increased
air loss, noise or vibration, which could be an indication that the tires need to be removed
from service to prevent tire failure.

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.
REMEMBER TO AVOID DAMAGE TO YOUR TIRES AND POSSIBLE ACCIDENT
• INSPECT TIRES AT LEAST MONTHLY, AND IMMEDIATELY AFTER STRIKING ANY ROAD HAZARD.
• C HECK TIRE PRESSURE AT LEAST ONCE EACH MONTH WHEN TIRES ARE COLD AND
B
EFORE EVERY LONG TRIP.
• N EVER UNDERINFLATE OR OVERINFLATE A TIRE.
•
NEVER OVERLOAD YOUR VEHICLE AND TIRES.
•
ALWAYS OBEY LEGAL SPEED LIMITS AND DRIVE AT A SPEED THAT IS REASONABLE
U
NDER THE ROAD AND WEATHER CONDITIONS.
• A VOID DRIVING OVER POTHOLES, OBSTACLES, CURBS OR EDGES OF PAVEMENT.
•
AVOID EXCESSIVE WHEEL SPINNING.
•
IF YOU SEE ANY DAMAGE TO A TIRE, REPLACE THE TIRE WITH A PROPERLY INFLATED
S
PARE AND VISIT A QUALIFIED TIRE PROFESSIONAL AT ONCE.
• K EEP TIRES AND WHEELS PROPERLY ALIGNED, BALANCED, AND ROTATED.
•
HAVE MOUNTING AND REPAIRS DONE BY A TIRE PROFESSIONAL.
•
IF YOU HAVE ANY QUESTIONS CONTACT YOUR BFGOODRICH® RETAILER.

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.

BRIDGESTONE® - FIRESTONE®

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.

BRIDGESTONE® - FIRESTONE®
45
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.

BRIDGESTONE® - FIRESTONE®
46
• 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.

BRIDGESTONE® - FIRESTONE®
47
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.
