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 9‑65 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.
