Tire Inspection
We recommend that you
regularly inspect your vehicle's
tires, including the spare tire,
if the vehicle has one, for signs
of wear or damage. See When It
Is Time for New Tires on
page 9‑63 for more information.
Tire Rotation
Tires should be rotated every
8 000 to 13 000 km (5,000 to
8,000 miles). See Scheduled
Maintenance on page 10‑2.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
Any time you notice unusual
wear, rotate the 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 9‑63 and Wheel
Replacement on page 9‑69.
When rotating the vehicle's tires,
always use the correct rotation
pattern shown here.
Do not include the compact
spare tire in the tire rotation.
