YOUR SPARE TIRE
Consult your vehicle Owner’s Manual for proper application of your
sp
are 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.
The spare tire in your vehicle is intended to be used as a spare when
n e

eded. 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
pr
essure 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
co
llect 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.
WARNING!
Check inflation pressure before use. Failure to have proper
in
flation pressure when using your spare tire can result in serious
personal injury or death. See Tire Inflation Pressure in this
manual.
WARNING!
Mounting a “temporary use” tire on a wheel which is not
sp
ecifically 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.

RFT TIRES WITH RUN-FLAT TECHNOLOGY
If your vehicle is equipped with
Bridgestone® or Firestone® brand
RF
T tires, this chapter presents
specific 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
ut
ilize 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
ap
ply, which varies according 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
fo
r 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
wi
th 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.

BRIDGESTONE® - FIRESTONE®

The vehicle or TPMS manufacturer may advise checking the TPMS
regularly to confirm 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 a Bridgestone® Firestone® Run-Flat Certified
Retailer for questions regarding TPMS operation and service.
RUN-FLAT OR LOW TIRE PRESSURE OPERATION
General Instructions
The Tire Pressure Monitoring System (TPMS) required in your vehicle
m a

y have different methods of alerting you when your tire has lost
inflation pressure. The international standard for the definition of
run-flat operation is pressure at or below 10 psi (70 kPa); however,
some vehicle manufacturers may have established a different pressure
limit. Consult your vehicle Owner’s Manual for the details of your
TPMS. Once the TPMS has indicated that a tire has reduced inflation
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 possible; do not
e
xceed 50 mph (80 km/h).The greater the speed, the less distance
t

he tire can travel.
• Avoid abrupt or aggressive acceleration, braking, or cornering
m
aneuvers as much as safely and reasonably possible. Pot holes
and other road hazards should be avoided. Careful driving limits
potential damage to the tire, wheel, and vehicle.
• Proceed to a safe and convenient location for tire service as soon
a
s possible. Take note of your mileage; your operation distance is
limited. See "Distance — How Far You Can Drive,” the next section
in this manual.
WARNING!
Serious personal injury or death may result from a tire failure or
ac
cident 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.

•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 will need to be replaced before proceeding.
• If towing a trailer, stop driving as soon as safely and reasonably
p
ossible. 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
h
ot). Allow the tire to cool before handling.
DISTANCE — HOW FAR YOU CAN DRIVE
Factors affecting run-flat or low tire pressure operating distance
in
clude vehicle speed, load, and maneuvering; the amount of inflation
pressure loss; the extent of any tire damage; and ambient temperature.
The tire may be marked on the sidewall with run-flat or low tire
pr
essure operating speed and/or distance limitations, which vary by
tire design and vehicle application (consult your vehicle owner’s
manual). By international standard, RFT tires have a baseline
limitation in run-flat mode of the following:

NOTE:

• Maximum distance values are determined under controlled condi -
tions, which may vary in actual use.
• Your mileage capability may be less, or more, depending on your
s
pecific operating conditions.
• If in doubt, do not exceed the 50
mile (80 km) limitation.
• Seek tire service as soon as possible to minimize tire damage.
Maximum Speed: 50 mph (80 km/h)
Maximum Distance: 50 miles (80 km)

SPECIAL SERVICE AND REPAIR ISSUES
Run-Flat Certified Retailers
Because of the advanced technology and design of Run-Flat tires and
th
e required Tire Pressure Monitoring Systems (TPMS), Bridgestone®
Firestone® Run-Flat Certified Retailers are specially trained to sell and
service RFT tires.
Run-Flat Certified Retailers have the necessary equipment and are
sp
ecially trained to properly mount and demount RFT tires and to
handle TPMS devices. Conventional mounting equipment may
irreparably damage RFT tires and an improper repair is unsafe and
will void the Limited Warranty. Accordingly, it is important to go to
a Bridgestone® Firestone® Run-Flat Certified Retailer for tire
maintenance and replacement.
Call toll-free 1-877-BFS-4RFT or, 87
7-237-4738 or visit

www.bridgestonetire.com
to locate the nearest Bridgestone®
Firestone® Run-Flat Certified Retailer.
Inspection after Run-Flat or Low Pressure Operation
Following run-flat or low tire pressure operation, or in the event of
an
y 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 per the recommendations in this manual (see “Radial Tire
Ro

tation”). 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
em
ergency/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 specifications 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
ca
n be ultimately rendered unusable due to a puncture or other road
hazard as well as from improper run-flat or low tire pressure
operation. Some punctures may be repaired under certain restrictions
and prescribed procedures.
When driven flat or with low pressure, factors affecting reparability
in
clude 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
o
r bead areas.
• Abrasion, wrinkling, or separation is present on the tire interior.
•
Any condition or damage is present that disqualifies repair of a
c
onventional tire.
Run-Flat Certified Retailers will 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 the section “Tire
Repairs” in this manual.

NOTE:

Some vehicle manufacturers do not recommend using repaired tires.
Co
nsult your vehicle Owner’s Manual or contact the vehicle manufac -
turer before operating a repaired tire on your vehicle.

DOT Symbol and Tire Identification Number: The “DOT” symbol
constitutes a certification that the tire conforms to applicable US
Department of Transportation (DOT) motor vehicle safety standards
(for tires). Following the “DOT” symbol is the tire identification
number, also known as the DOT serial number or code. For example:
* For tires produced from 2000-on. In the example above, the tire was
p r

oduced in the 18th week of 2000. For tires produced prior to 2000,
there is one digit in group (f) which identifies the last digit of the year
of production, i.e. “329” would likely signify the 32nd week of 1999,
but could possibly signify the 32nd week of 1989. If in doubt, consult
a qualified tire service professional.
The DOT symbol and tire identification number can be found on at
le
ast one sidewall near the wheel. The other sidewall may have a
partial serial code that excludes (e) and (f) above.
Maximum Load and Inflation: T
he maximum load and maximum
inflation pressure is marked on each sidewall in metric and English
units. For example:
MAX LOAD 685 kg (1,510 lbs) AT 240 kPa (35 psi) MAX PRESS

NOTE:

The load and inflation values marked on the tire sidewall are
ma
ximum permissible values for the tire only. Never assume that
these values are the actual maximum load capacity or recommended
tire pressure values for your vehicle. See “Tire Inflation Pressure,”
“Tips for Safe Tire Inflation,” and “Tips for Safe Loading” in this
manual.

Temperature
The temperature grades are A (the highest), B, and C, representing the
ti
re’s resistance to the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can cause the
material of the tire to degenerate 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 laboratory test
wheel than the minimum required by law.
WARNING!
The temperature grade is established for a tire that is properly
in
flated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination, can cause
heat buildup and a possible tire failure.
