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 6‑69 for more information.
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km). See Scheduled Maintenance
on page 7‑3.
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. SeeWhen It Is Time for New Tires on
page 6‑69 and Wheel Replacement on page 6‑74
for more information.
Four‐Tire Rotation Pattern
If your vehicle has a compact spare tire, it should
not be included in the tire rotation process.
Use the four‐tire rotation pattern shown.
