TIRE CHAINS
Install chains on rear tires only. Tire chains may be
installed on all models except the Sahara and Rubicon.
Follow these recommendations to guard against damage
and excessive tire and chain wear:
• Use chains on P225/75R16 tires only. P255/75R17,
P255/70R18, and LT255/75R17 tires do not provide
adequate clearance.
• Use SAE class “S” tire chains or traction devices only.
• Chains must be the proper size for the vehicle, as
recommended by the chain manufacturer.
• Follow tire chain manufacturer’s instructions for
mounting chains.
• Install chains snugly and tighten after 0.6 mile (1 km)
of driving.
• Do not exceed 30 mph (48 km/h).
• 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.
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals. More frequent rotation is
permissible if desired. The reasons for any rapid or
unusual wear should be corrected prior to rotation being
performed.
