visible damage. Bumps, bulges, or cracks in any tire may indicate
detachment within the tire body and require inspection by a qualified
tire professional. If any tire, including the spare, has bumps, bulges, \
cracks, or other visible damage, do not resume driving with that tire. I\
f
you have no other option, you should drive as slowly and cautiously as
possible until you can obtain towing or mechanical assistance. If the
spare tire is not properly inflated, do not resume driving with that tire
unless you have no other option, in which case you should drive only
as slowly as is safely possible in the traffic conditions until you can
both get the spare tire properly inflated and have it checked by a tire
professional to ensure that it is safe to use.
Proper Inflation
Driving on Any Tire That Does Not Have the Correct
Inflation Pressure Is Dangerous
An underinflated tire builds up excessive heat that may result in
sudden tire failure and an accident. If your tires are those that came
as original equipment on your vehicle when it was new, refer to the tire
information placard that came on your vehicle (located in the vehicle’s
door jamb, inside the fuel hatch, or on the glove compartment door),
for the recommended operating pressures. For replacement tires, ask
your BFGoodrich tire retailer for the correct inflation pressure; if you
do not, refer to the tire information placard that came on your vehicle \
(located in the vehicle’s door jamb, inside the fuel hatch, or on the
glove compartment door), for the recommended operating pressures.
These inflation pressures must be maintained as a minimum. Never
exceed the Maximum Pressure rating stated on the tire sidewall. Note
that proper inflation pressures for rear tires may differ from proper
inflation pressures for front tires. The Maximum Pressure rating on
the tire is normally not equal to the placard pressure.

BFGOODRICH TIRE
Check the Cold Inflation Pressure in All Your Tires,
Including the Spare, at Least Once Each Month
Failure to maintain correct inflation may result in improper vehicle
handling and may cause rapid and irregular tire wear, sudden tire
failure, loss of vehicle control, and an accident. Therefore, inflation
pressures should be checked at least once each month and before
every long-distance trip. This applies to all tires, including sealant types
and self-supporting tires, which are as susceptible to losing inflation as
any other type of tire if not properly maintained. Pressures should be
checked before the tires have been driven on or after they have been
allowed to cool down to the ambient air temperature. Driving for even
a short distance causes tires to heat up and their inflation to increase,
and recommended tire pressures are for tires that have not been
heated by recent driving on them.
Underinflation and Overinflation Must Be Checked
with a Tire Pressure Gauge
Tires must be checked monthly with a tire pressure gauge. It is
impossible to determine whether tires are properly inflated by simply
looking at them. It is almost impossible to feel or hear when a tire is \
being run underinflated or overinflated. Use an accurate tire pressure
gauge to check tire pressure each month. Small and inexpensive tire
pressure gauges are available. You should keep one in your vehicle’s
glove box or trunk and use it monthly and as otherwise needed.
Tire Pressure Monitoring Systems (TPMS)
Your vehicle is likely equipped with a Tire Pressure Monitoring System
(TPMS) that is designed to monitor the pressure of tires mounted on
your vehicle and sends a signal to the driver if a tire pressure falls
below a predetermined level. A TPMS should not replace monthly
manual pressure checks for all four tires and the spare. You should
manually monitor and check tire pressure inflation with a pressure
gauge. Your tires should have the recommended pressure listed by
your vehicle’s manufacturer. This information can be found in the
vehicle owner’s manual and is on a placard located in the vehicle’s

Always consult the tire manufacturer for the maximum speed of
Unlimited Z or (Y) tires. Speed rating is identified as a part of the tire’s
sizing or service description. Exceeding the lawful speed limit is neith\
er
recommended nor endorsed.
In the latest attempt to standardize tire designations, all ratings exce\
pt
Unlimited Z incorporate the speed symbol and load index as the tire’ s
service description.
For Example:
“Z” Rated Tires
When “Z” appears in the size description with the service descript\
ion,
the maximum speed is indicated by the service description.
Examples:
For tires having a maximum speed capability above 240 km/hr
(149 mph), a “Z” may appear in the size designation.
For tires having a maximum speed capability above 300 km/hr
(186 mph), a “Z” must appear in the size designation and the service
description must include Y in parenthesis. Example: 275/40ZR18
(99Y). Consult the tire manufacturer for maximum speed when there
is no service description.

pattern, observe the arrows molded on the sidewall that show the
direction in which the tire should rotate.
Care must be taken to maintain the proper rotation direction. Some
Tire Pressure Monitoring Systems (TPMS) may not recognize that
a tire has been moved to a different position on your vehicle. Make
certain that your TPMS system is reset, if necessary, so as to correctly
identify the location of each tire on your vehicle. Refer to your vehicl\
e
owner’s manual or your vehicle dealer for this information. Determine
whether rotated tires require tire inflation adjustment, because front
and rear position tire pressure may vary according to the vehicle
manufacturer’s specification due to the actual load on that wheel
position. Some vehicles may have tires of different size mounted on
the front versus the rear axles, and these different tires have rotation
restrictions. Always check the vehicle owner’s manual for the proper
rotation recommendations.
Full-Size Spare
Full-size spare tires (not temporary spares) of the same size and
construction should be used in a five-tire rotation and should be
inspected by a tire professional during routine tire inspection. Always
have spare tires inspected before installation. Tires are composed
of various types of rubber compounds and other materials having
performance properties essential to the proper functioning of the tire. \
These component properties change over time. Always check the
inflation pressure of the full-size spare and look for any indication of
cracking or other damage immediately before incorporating the spare
into rotation. If you see any damage, or if the tire is underinflated, do
not resume driving with that tire unless you have no other option, in
which case you should drive only as slowly as is safely possible in the \
traffic conditions until you can both get the spare tire properly inflated
and have it checked by a tire professional to ensure that it is safe
to use. Follow the vehicle manufacturer’s recommended pattern for
rotation. If such a recommendation is unavailable, see a qualified
tire professional.

Tire Repairs
Whenever a Repair Is Needed, Immediately See Your
BFGOODRICH
® Tire Retailer or, If One Is Not Readily
Available, Another Qualified Tire Professional
If any BFGOODRICH® tire sustains a puncture, have the tire
demounted and thoroughly inspected by a qualified tire professional
for possible damage that may have occurred. A tread area puncture
in any BFGOODRICH
® passenger or light truck tire can be repaired
if the puncture hole is not more than 1/4” 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 U.S. Tire Manufacturers Association’s recommended
repair procedures.
Repairs of all tires must be of the combined-plug-and-inside-patch
type. Your BFGOODRICH tires must be removed from the wheel for
inspection prior to repair. Plug-type repairs made on a tire that remains
mounted on a wheel are improper and can result in an accident. 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 and can
result in an accident. An improperly repaired tire may 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 and result in an accident. Never \
repair a tire with less than 2/32nds of an inch of tread remaining. At this
tread depth, the tire is worn out and must be replaced.

year of decade, e.g.: 1995, 1985, etc.) For the 1990-1999 decade
BFGOODRICH® brand tires are marked with a triangle pointing to the
last three numeric characters. Tires produced after July 2000 have an
additional digit to identify a given decade. For example, 2800 means
the tire was produced during the 28th week of 2000; 0201 during the
2nd week of 2001. If the last digits of your DOT number contain three
numeric characters and are not marked with a triangle, consult a
qualified tire professional to determine the year of manufacture.
Service Life and Safety for Passenger Car and Light
Truck Tires Including Spare 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 (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. That is why, in addition to regular inspections and
inflation pressure maintenance by consumers, it is recommended that
passenger car and light truck tires, including spare tires be inspected \
regularly by a qualified tire specialist, such as a BFGoodrich tire
retailer, who will assess the tire’s suitability for continued service.
Tires which have been in use for 5 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 and
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 that any tires in service 10 years or more from the date
of manufacture, including spare tires, be replaced with new tires as
a precaution even if such tires appear serviceable and even if they

BFGOODRICH TIRE
have not reached the legal wear limit. For tires that were on an origina\
l
equipment vehicle (i.e., acquired by the consumer on a new 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. Consumers
should locate the Department of Transportation or “DOT” code on the
tire. The code begins with “DOT” and ends with the week and year of
manufacture. For example, a DOT code ending with “2214” indicates
a tire made in the 22nd week of 2014.
Remember . . . to Avoid Damage to Your Tires and
Possible Accident:
• INSPECT TIRES AT LEAST MONTHLY, AND IMMEDIATELY
AFTER STRIKING ANY ROAD HAZARD.
•
CHECK TIRE PRESSURE AT LEAST ONCE EACH MONTH
WHEN TIRES ARE COLD AND BEFORE EVERY LONG TRIP.
•
NEVER UNDERINFLATE OR OVERINFLATE A TIRE.
•
NEVER OVERLOAD YOUR VEHICLE AND TIRES.
•
ALWAYS OBEY LEGAL SPEED LIMITS AND DRIVE AT A SPEED
THAT IS REASONABLE UNDER THE ROAD AND WEATHER
CONDITIONS.
•
AVOID 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 SPARE AND VISIT A QUALIFIED
TIRE PROFESSIONAL AT ONCE.
•
KEEP 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 TIRE RETAILER.
