Inspect tires regularly for signs of wear or damage. Also inspect the spare tire. For more information on tire inspection, see When It Is Time for New Tires .

Rotating vehicle tires helps them to wear evenly and keeps the vehicle performing like it did when tires were new.

Rotate the tires and check wheel alignment approximately every 5,000 to 8,000 miles (8 000 to 13 000 km) or when unusual tire wear is noted. See "Scheduled Maintenance" in the Index of the "Limited Warranty, Maintenance and Owner Assistance Information" manual for more information. Also check the wheels for damage, see Wheel Replacement for more information.

Use this pattern when rotating the vehicle tires. Do not include the compact spare tire in the tire rotation.

Caution : Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel bolts become loose after time. The wheel could come off and cause a crash. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle using a scraper or wire brush.

Installing wheels with a good metal-to-metal contact at the mounting surfaces is necessary to prevent wheel bolts from becoming loose.

To prevent corrosion or rust build-up, lightly coat the wheel hub center and the cone-shaped surface of each wheel bolt with wheel bearing grease, after a wheel change.

See Changing a Flat Tire for information on installing the tire and wheel assembly. Also see "Wheel Bolt Torque" under Capacities and Specifications .

Adjust the front and rear tires to the recommended cold tire inflation pressure shown on the Tire and Loading Information label. See Inflation - Tire Pressure and Loading the Vehicle .
