CAUTION! (Continued)
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 pave-
ment.
Observe the traction device manufacturers instruc-
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested
operating speed of the device manufacturers if it is
less than 30 mph (48 km/h).
Do not use traction devices on a compact spare tire.
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 aggres-
sive 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.
Refer to the “Maintenance Plan” for the proper mainte-
nance intervals. The reasons for any rapid or unusual wear
should be corrected prior to rotation being performed.
The suggested Front Wheel Drive (FWD) 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.
The suggested Four Wheel Drive (4WD) Tire rotation
method is the “rearward cross” shown in the following
diagram.
