Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle’s tires, including the spare tire, for signs of
wear or damage. See When It Is Time for New
Tires on page 5-65 for more information.
Tire rotation is not recommended if your vehicle
has the following tire combinations:
•
P235/65R17 size tires on the front wheels and
P255/60R17 size tires on the rear wheels.
•
P235/60R18 size tires on the front wheels and
P255/55R18 size tires on the rear wheels.
Different tire sizes should not be rotated front
to rear. Each tire and wheel should only be used
in its original front or rear position.
Tire rotation is recommended if your vehicle is
equipped with P255/50R20 size tires on all
four wheel positions. These tires should be rotated
every 5,000 to 8,000 miles (8 000 to 13 000 km).
See Scheduled Maintenance on page 6-4.
The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This
will ensure that your vehicle continues to perform
most like it did when the tires were new.
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
See When It Is Time for New Tires on page 5-65
and Wheel Replacement on page 5-70.
When rotating P255/50R20 size tires, always use
the correct rotation pattern shown here.
Do not include the compact spare tire in the
tire rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire
and Loading Information label. See Inflation - Tire
Pressure on page 5-56 and Loading the Vehicle on
page 4-30.
