Jeep 2009 Commander - Manual (Page 357)

• Do not install tire chains or traction devices on ve-
hicles with larger than 235/65R17XL size tires. 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.
The suggested rotation method is the “forward-cross”
shown in the following diagram.
