Tire Chains - Jeep 2009 Grand Cherokee Owner's Manual

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

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:
STARTING AND OPERATING 343
Do not install tire chains or traction devices on ve-
hicles with larger than P235/65R17 tires. Tires larger
than this may not provide 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 0.5 mile (1 km)
of driving.
Do not exceed 30 mph (48 km/h), unless otherwise
specified by the chain manufacturer.
Drive cautiously, avoiding large bumps, potholes and
extreme driving maneuvers.
