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.

TIRE FAILURE WHILE DRIVING
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
turning forces. The vehicle manufacturer recommends the inflation pressures for the
tires mounted on your vehicle.
These situations can cause a tire failure, even at a later date, which could lead to serious
pe
rsonal 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:
• A dversely affect vehicle ride and handling.
•
Reduce tire tread wear.
•
Affect fuel economy.
T
herefore, follow these important recommendations for tire and vehicle safety, mileage,
a n
d economy:
• Always keep the vehicle manufacturer’s recommended inflation pressure in all your
t
ires, including the spare.
• Check their pressure monthly and before long trips or carrying extra weight.
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 sudden tire failure, the following information should be helpful:
• W hen the failure occurs, you may hear a loud noise, feel a vibration, and/or the
v
ehicle may pull toward the side of the failed tire.
• D O NOT abruptly brake or turn.
•
Slowly remove your foot from the accelerator, hold the steering wheel firmly, and
s
teer to maintain your lane position.
• O nce 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
p
ossible.
WARNING!
Driving on tires with improper inflation pressure is dangerous.
• U nder-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
i
mpact.

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.

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:
NOTE:
• Never include a “temporary use” spare tire in the rotation.
•
Tires with directional tread patterns must be rotated so the direction of revolution
d
oes not change; this may require demounting/mounting the tires.
• S pecial attention should be given if your vehicle is equipped with a Tire Pressure Moni -
t
oring System (TPMS). Rotation of your tires may affect the system; consult your
v e
hicle Owner’s Manual or a qualified tire service professional.
• S ome vehicles may have different size tires/wheels on front and rear which would
r
estrict rotation. Always check and follow the vehicle manufacturer’s rotation recom -
mendation.
• T o use a full-size spare in the rotation pattern on vehicles with dual rear wheels,
c
onsult your vehicle Owner’s Manual for the recommended procedures or consult the
vehicle manufacturer.
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.
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.

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
for more information.
The spare should be included in regular tire inspections and inflation pressure checks.
In
addition, it should be replaced 10 years after date of manufacture, regardless of
condition or tread depth. For more information, see the “Tire Damage, Inspection and
Service Life” in this manual.
TIRE STORAGE
Tires should be stored indoors in a cool, dry place where water cannot 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.
The spare tire in your vehicle is intended to be used as a spare when needed. The spare
t i
re 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 identification numbers have
been recorded; fill 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.
RFT TIRES WITH RUN-FLAT TECHNOLOGY
If your vehicle is equipped with Bridgestone® or Firestone® brand RFT
tires, this chapter presents specific maintenance and safety issues
a s
sociated 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
d e
signed 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 varies
ac
cording to the specific 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: B
ridgestone® 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 maintenance for safe operation
an
d 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 Run Flat
tires. 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
following section in this manual.
