Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). 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 5-66 and Wheel Replacement on page 5-69 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 on page 6-4. Directional Tires If your vehicle has 215/45ZR17 size tires, they are directional tires and must roll in a certain direction for the best overall performance. The direction is shown by an arrow on the tire sidewall. Because these tires are directional, they should be rotated as shown here. These tires should only be moved from front to rear and rear to front on the same side of the vehicle. Do not include the compact spare tire in your tire rotation. Non-Directional Tires When rotating non-directional tires, always use the correct rotation pattern shown here. 5-65
