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 426 and Wheel Replacement on page 432 for more information. Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrench to tighten the cable. For information on storing or removing the spare tire, see Changing a Flat Tire on page 436. 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 479. When rotating your tires, always use the correct rotation pattern shown here. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. See Loading Your Vehicle on page 330, for an example of the label and its location on your vehicle. The Tire Pressure Monitor System (TPMS) sensors will need to be reset after a tire rotation. See "TPMS Sensor Identification Codes" under Tire Pressure Monitor System on page 420. 425
