SERVICING AND MAINTENANCE 383
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 332. The
reasons for any rapid or unusual wear should be corrected
prior to rotation being performed.
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.
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 condi-
tion 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).
Autosock traction devices do not require
retightening.
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.
CAUTION!
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type, and circumference on each
wheel. Any difference in tire size can cause damage to
the transfer case. Tire rotation schedule should be
followed to balance tire wear.
