Jeep 2010 Commander - Owner Manual - Manual (Page 302)

• For vehicles equipped with 18 inch wheels, do not
install tire chains or traction devices on tires larger
than 235/60R18XL. Tires larger than this may not
provide sufficient body clearance with chains or other
traction devices.
• Manufacturer recommends a cold inflation pressure of
38 psi (262 kPa) when using 235/65R17XL size tires for
this vehicle.
• 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 mi (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.
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 “Maintenance Schedule” in Section 8 of this
manual for the proper maintenance intervals. More fre-
quent rotation is permissible if desired. The reasons for
any rapid or unusual wear should be corrected prior to
rotation being performed.
