Tire Inspection and Rotation
Tire rotation is not recommended if your vehicle is a
GXP model equipped with P255/45R18 size tires on
the front wheels and P225/50R18 size tires on the rear
wheels. Different tire sizes front to rear should not
be rotated.
Tire rotation is recommended if the original equipment
tires installed on your vehicle are of the same size
and type on all four tire/wheel positions. Original
equipment tires of the same size and type should be
rotated every 5,000 to 8,000 miles (8 000 to 13 000 km).
Any time you notice unusual wear, rotate your vehicle’s
tires as soon as possible and check the wheel
alignment. Also check for damaged tires or wheels. See
When It Is Time for New Tires on page 5-71 and
Wheel Replacement on page 5-75 for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See Scheduled Maintenance
on page 6-4 for scheduled rotation intervals.
The correct rotation pattern shown here is only for
non-GXP tires.
Do not include the compact spare tire, if equipped, in
your vehicle’s tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire and
Loading Information label, and reset the Tire Inflation
Monitor System. See Tire Inflation Monitor System
on page 5-68 for additional information.
