Tire Inspection and Rotation
Inspect tires regularly for signs of wear or damage.
Also inspect the spare tire, if the vehicle has one.
For more information on tire inspection, see When It
Is Time for New Tires on page 5-81.
Tire rotation is not recommended if the vehicle
has 255/40R19 size tires on the front wheels and
285/35R19 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 the vehicle has
the same 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 5-81
and Wheel Replacement on page 5-86.
Use the rotation pattern shown here when rotating
tires of the same size installed on all four wheel
positions.
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 5-72 and Loading the Vehicle on
page 4-21.
