Tire Chains; Tire Rotation Recommendations - Jeep 2004 Grand Cherokee Owner's Manual

220 STARTING AND OPERATING

TIRE CHAINS

Certain models have sufficient tire-to-body clearance to
allow use of tire chains. Install chains on rear tires only.
Follow these recommendations to guard against damage
and excessive tire and chain wear:
• Do not install tire chains or traction devices on ve-
hicles with larger than P225/75R16 size tires. These
tires are too large for sufficient body clearance with
chains or other traction devices.
• Use SAE class "S" tire chains or traction devices only.
• Follow tire chain manufacturer's instructions for
mounting chains.
• Install chains snugly and tighten after 1/2 mile (1 km)
of driving.
• Do not exceed 35 mph (56 km/h), unless otherwise
specified by the chain manufacturer.
• Drive cautiously, avoiding large bumps, potholes and
extreme driving maneuvers.

TIRE ROTATION RECOMMENDATIONS

Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates, and develop irregular wear patterns.
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 main-
tain mud, snow, and wet traction levels, and contribute to
a smooth, quiet ride.
Follow the recommended tire rotation frequency for your
type of driving found in the "Maintenance Schedules"
Section of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual wear
should be corrected prior to rotation being performed.
