Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km).

If your vehicle has P245/45ZR18 96W size tires, GM recommends rotating these tires at 3,000 mile (4 800 km) intervals. These tires are optimized for dry traction and handling performance. Tread life may be 15,000 miles (24 140 km) or less for these tires, depending on how and where you drive.

Any time you notice unusual wear, rotate your vehicle's tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires and Wheel Replacement for more information.

The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See Scheduled Maintenance .

When rotating your vehicle's tires, always use the correct rotation pattern shown here.

If your vehicle has a compact spare tire, do not include it in the tire rotation.

After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. See Loading the Vehicle , for an example of the tire and loading information label and its location on your vehicle.

If your vehicle has the Tire Pressure Monitor System (TPMS) the TPMS sensors will need to be reset and matched to the tire/wheel position. A special TPMS diagnostic tool is used to reset the sensor identification codes. See your dealer for service.

Make certain that all wheel nuts are properly tightened. See "Wheel Nut Torque" under Capacities and Specifications .

Caution: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See Changing a Flat Tire .
