Rotating the tires
NOTE: Use the five tire rotation only when the
conventional spare wheel is the same as road
wheels. (Do not mix the steel wheel with
aluminum wheels in tire rotation sequence).
WARNING
Do not use the temporary spare tire in
the tire rotation.
Replacing the Tires
Replace any tires that show wear bands. When your
tire shows a wear band, it has only 1/16 inch (2
mm) of tread left.
