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.

Replacement of Two Tires
All four tires should be replaced at the same time. However, if only
two tires are replaced, the new ones should be put on the rear.
Deeper tread tires on the rear axle provide better handling, wet grip
and evacuate water, thereby helping to avoid oversteer and loss of
vehicle stability on wet surfaces. Deeper tread tires on the front axle \
can improve wet straight line braking and stopping distance. If only two\

tires are being replaced, BFGoodrich generally recommends they be
installed on the rear axle in the absence of a tire service professional’s
recommendation or consumer’s preference to the contrary.
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 different characteristics, failure to
operate your SUV or truck in a proper and safe manner can increase
the likelihood of vehicle rollover. Modifications to your SUV or truck
tire size, tire type, wheels or suspension can change your vehicle’ s
handling characteristics and further increase the likelihood of vehicle \
rollover. Whether your SUV or 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 proper performance, leading to tire damage
that can result in an accident. Tires that become unserviceable due
to alterations such as truing, whitewall inlays, addition of balancing

BFGOODRICH TIRE
Storage
Tires contain materials to protect their outer surfaces from ozone
and weather checking. As the tire rolls and flexes, those materials
continually migrate to the surface, replenishing this protection
throughout the normal use of the tire. Consequently, when tires sit
outdoors, unused for long periods of time (a month or more), their
surfaces become dry and more susceptible to ozone and weather
checking, and the casing becomes susceptible to flat spotting. For
this reason, tires should always be stored in a cool, dry, clean, indoor
environment. If storage is for one month or more, eliminate the weight
from the tires by raising the vehicle or by removing the tires from the \
vehicle. Failure to store tires in accordance with these instructions
could result in damage to your tires or premature aging of the tires
and sudden tire failure. When tires are stored, be sure they are placed \
away from sources of heat and ozone such as hot pipes and electric
generators. Be sure that surfaces on which tires are stored are clean
and free from grease, gasoline or other substances which could
deteriorate the rubber. Tires exposed to these materials during storage
or driving could be subject to sudden failure.
One reason why your spare tire should be included in the tire rotation
schedule is that temperatures in a vehicle’s closed trunk, especially
in sunny geographical areas, can become high enough so that, over
a sustained period, they can cause small cracks or other changes to
the properties of a tire stored in the trunk. An accumulation of such
changes can weaken the tire and, especially if the tire is not kept
properly inflated, make it unsafe to use when it is needed.
Proper Tire Mounting
Tire mounting can be dangerous and must be done by professionally
trained persons using proper tools and procedures as specified by the
U.S. Tire Manufacturers Association.
Your tires should be mounted on wheels that are the correct size
and type and are in good, clean 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.

You should visually inspect your tires on a regular basis throughout
their life, and you should 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:•
After striking anything unusual in the roadway, have a qualified tire
service professional demount the tire and inspect it for damage. A
tire may not have visible signs of damage on the tire surface. Yet,
the tire may suddenly fail without warning, a day, a week, or even
months later.
•
Inspect your tires for cuts, cracks, splits or bruises in the tread and \
sidewall areas. Bumps 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.
•
Inspect your tires for adequate tread depth. When the tire is worn
to the built-in indicators at 2/32 inch (1.6 mm) or less tread groove
depth, or the tire cord or fabric is exposed, the tire is dangerously
worn and must be replaced immediately.
•
Inspect your tires for uneven wear. Wear on one side of the tread
or flat spots in the tread may indicate a problem with the tire or
vehicle. Consult a qualified tire service professional.
•
Inspect your wheels also. If you have a bent or cracked wheel,
it must be replaced.
•
Don’t forget to check the spare tire.
Make sure your tires, including the spare tire, continue to be regularly\

inspected after 5 years 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 wi\
th
new tires.
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

For vehicles with a “temporary use” spare tire, follow the vehicle\

manufacturer’s recommended pattern for rotation, or, if not provided,
the following may be used:
If your spare is the same size, load rating, and type of tire as your ro\
ad
tires, it should be included in the tire rotation process. For vehicles \
with
a “full-size” spare, the following rotation pat- terns may be used:
FULL SIZE SPAREFULL SIZE SPARE
Note:
•
Never include a “temporary use” spare tire in the rotation.
•
Tires with directional tread patterns must be rotated so the
direction of revolution does not change; this may require
demounting/mounting the tires.
•
Special attention should be given if your vehicle is equipped with
a Tire Pressure Monitoring System (TPMS). Rotation of your tires
may affect the system; consult your vehicle owner’s manual or a
qualified tire service professional.
•
Some vehicles may have different size tires/wheels on front and
rear which would restrict rotation. Always check and follow the
vehicle manufacturer’s rotation recommendation.

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
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
utilize 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
apply, 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 : Bridgestone and Firestone brand tires
are marked on the sidewalls, near the wheel, with the RFT logo
(shown above).

Have your tire 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, resulting in an accident.
Old valves may leak. When new tubeless tires are mounted, have
new valves of the correct type installed. Tubeless tires must be
mounted only on wheels designed for tubeless tires, i.e., wheels that

• Find a safe place to pull off the road and allow the vehicle to
gradually decelerate. Apply light braking as required to stop safely.
•
Gradually pull over to the shoulder and come to a stop. Look for a
damaged tire on your vehicle.
•
Seek roadside assistance or change the damaged tire with your
spare tire.
•
Have all of your tires and the vehicle thoroughly inspected by a
tire professional.
TIRE ROTATION
The purpose for rotating tires is to achieve more uniform wear for all
tires on a vehicle. Your tires should be thoroughly examined on a lift by
a tire dealer for any abnormalities. If tires show uneven treadwear, ask
the service person to check and/or correct any vehicle wheel alignment
or other mechanical problem before rotation.
The following rotation patterns are acceptable. Please refer to your
vehicle Owner’s Manual for rotation advice.

NITTO TIRE
171
Full-size spare tires (not temporary spares) of the same size,
construction, and speed rating may be used in a five-tire
rotation pattern.
After rotation, check the inflation pressure of all the tires. The front
and rear tire pressures may vary according to the vehicle
manufacturer’s specifications.
Remember to follow your vehicle Owner’s Manual for tire rotation
intervals. Your Limited Warranty recommends Nitto brand tires to be
rotated as follows:
•
Every 3,500 miles or less for high performance (low profile) tires.
•
Every 7,500 miles or less for standard passenger and light
truck tires.
More frequent rotation or a thorough vehicle inspection may be
necessary if, upon inspection, irregular or erratic treadwear is
beginning to appear.
It is important to remember the following: •
These tire rotation recommendations do not take into account
different tire and construction types mixed on the vehicle.
•
Some tires cannot be rotated in the manner described. Such tires
include unidirectional tires. Unidirectional tread patterns must be
rotated front-to-rear only so that the direction of revolution does
not change.
•
Some vehicles are designed with different tire sizes on the front
and rear axles. Normally, such combinations will not allow rotation.
Prior to rotating, consult the vehicle Owner’s Manual.
•
For vehicles with dual rear wheels, see the vehicle Owner’s
Manual for the vehicle manufacturer’s procedures. If your vehicle
Owner’s Manual is not available, please contact the vehicle
manufacturer.
•
Some vehicles are equipped with wheels that limit the choice of
rotation pattern. Consult the vehicle Owner’s Manual.
•
Do not include temporary spare tires in the rotation pattern.
However, if your spare tire is the same size and type as a road tire
(for LT tires of the same size, type, and load rating), it should be
