340 SERVICING AND MAINTENANCE
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off-Road
type tires. Rotation will increase tread life, help to
maintain mud, snow, and wet traction levels, and
contribute to a smooth, quiet ride.
For the proper maintenance intervals
Ú page 290. More
frequent rotation is permissible if desired. The reasons for
any rapid or unusual wear should be corrected prior to
rotation being performed.
NOTE:
The premium Tire Pressure Monitoring System will auto-
matically locate the pressure values displayed in the
correct vehicle position following a tire rotation.
The suggested rotation method is the “rearward cross”
shown in the following diagram.

UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in
addition to these grades.
WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
Because of restricted traction device clearance
between tires and other suspension components, it is
important that only traction devices in good condition
are used. Broken devices can cause serious damage.
Stop the vehicle immediately if noise occurs that
could indicate device breakage. Remove the
damaged parts of the device before further use.
Install device as tightly as possible and then retighten
after driving about ½ mile (0.8 km).
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
Do not drive for a prolonged period on dry pavement.
Observe the traction device manufacturer’s instruc-
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested
operating speed of the device manufacturer’s if it is
less than 30 mph (48 km/h).
Do not use traction devices on a compact spare tire.
