Tire Rotation
Because your vehicle's front and rear tires
perform different jobs, they often wear
differently. To make sure your tires wear evenly
and last longer, rotate them as indicated in the
following diagram.
For tire rotation intervals, see the Maintenance
Schedule booklet. If you notice that the tires wear
unevenly, have them checked.
In situations where the tires differ from front to
rear (snow/traction), simply rotate using a side
to side pattern.
Tire rotation pattern
After each rotation, adjust individual tire
pressure as specified on the Safety Compliance
Certification Label. Tighten wheel lug nuts to the
required torque specification and retighten again
after 500 miles (800 km).
