Tire Inspection and Rotation 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 on page 6-64 for more information. Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). See Scheduled Maintenance on page 7-3. 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 tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 6-64 and Wheel Replacement on page 6-68 for more information. Four-Tire Rotation Pattern If your vehicle has a compact spare tire, it should not be included in the tire rotation process. Use the four-tire rotation pattern shown. Five-Tire Rotation Pattern 6-62
