Tire Inspection and Rotation

Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
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 455
and Wheel Replacement on page 460 for
more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, use the wheel wrench to tighten the cable.
For information on storing or removing the
spare tire, see Changing a Flat Tire on page 465.
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 507.
