Tires should be rotated every 12 000 km (7,500 mi). The first rotation is the most important.
See Maintenance Schedule on page 11-3.
Tires are rotated to achieve a more uniform wear for all tires.
Anytime unusual wear is noticed, rotate the tires as soon as possible, check for proper tire inflation pressure, and check for damaged tires or wheels. If the unusual wear continues after the rotation, check the wheel alignment. See When It Is Time for New Tires on page 10-49 and Wheel Replacement on page 10-54.

Use this rotation pattern when rotating the tires.
Adjust the front and rear tires to the recommended inflation pressure on the Tire and Loading Information label after the tires have been rotated. See Tire Pressure on page 10-43 and Vehicle Load Limits on page 9-9.
Reset the Tire Pressure Monitor System. See Tire Pressure Monitor Operation on page 10-45.
Check that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications on page 12-2.
Warning
Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause a crash. When changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, a cloth or a paper towel can be used, however, use a scraper or wire brush to remove all rust or dirt.
Lightly coat the center of the wheel hub with wheel bearing grease after a wheel change or tire rotation to prevent corrosion or rust build-up. Do not get grease on the flat wheel mounting surface or on the wheel nuts or bolts.
