WARNING! (Continued)
• Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
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.
