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 5-70 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 6-4. 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 the 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 5-70 and Wheel Replacement on page 5-74. If your vehicle has dual rear wheels, also see Dual Tire Operation on page 5-61. Single Rear Wheels If your vehicle has single rear wheels, always use the correct rotation patterns shown here when rotating your vehicle's tires. Do not include the spare tire in the tire rotation, if the spare tire/wheel assembly does not match your vehicle's road tires and wheels in size and type. 5-68
