258 SERVICING AND MAINTENANCE
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device clear-

ance between tires and other suspension
components, it is important that only trac-
tion 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). 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.
CAUTION! (Continued)
Observe the traction device manufacturer's

instructions 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.

IRE OTATION
The tires on the front and rear of your vehicle
operate at different loads and perform different
steering, driving, 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 all season type tires. Rotation will
increase tread life, help to maintain mud, snow
and wet traction levels, and contribute to a
smooth, quiet ride.

ECOMMENDATIONS
Refer to the Maintenance Plan for the proper
maintenance intervals Ú page 212. The
reasons for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested rotation method is the "forward
cross" shown in the following diagram. This
rotation pattern does not apply to some
directional tires that must not be reversed.
