GM Service Manual Online
For 1990-2009 cars only

We recommend that you regularly inspect your vehicle's tires, including the spare tire, for signs of wear or damage. See When It Is Time for New Tires for more information.

Tire rotation is not recommended if your vehicle is a GXP model equipped with P255/45R18 size tires on the front wheels and P225/50R18 size tires on the rear wheels. Different tire sizes front to rear should not be rotated.

Tire rotation is recommended if the original equipment tires installed on your vehicle are of the same size and type on all four tire/wheel positions. Original equipment tires of the same size and type should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). See Scheduled Maintenance .

The purpose of a regular tire rotation is to achieve a uniform wear for all tires on the vehicle. This will ensure that your vehicle continues to perform most like it did when the tires were new.

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

Rotation Pattern for Non-GXP Tires Only


Object Number: 811106  Size: B2

The correct rotation pattern shown here is only for non-GXP tires.

Do not include a compact spare tire, if your vehicle has one, in the vehicle's tire rotation.

After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label, and reset the Tire Pressure Monitor System. See Tire Pressure Monitor System for additional information .

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 .
