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 5-67 for more information. Tire rotation is not recommended if your vehicle has the following tire combinations: • P235/65R17 size tires on the front wheels and P255/60R17 size tires on the rear wheels. • P235/60R18 size tires on the front wheels and P255/55R18 size tires on the rear wheels. Different tire sizes should not be rotated front to rear. Each tire and wheel should only be used in its original front or rear position. Tire rotation is recommended if your vehicle is equipped with P255/50R20 size tires on all four wheel positions. These 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 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 5-67 and Wheel Replacement on page 5-72. 5-66 When rotating P255/50R20 size tires, always use the correct rotation pattern shown here. Do not include the compact spare tire in the tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. See Inflation - Tire Pressure on page 5-59 and Loading Your Vehicle on page 4-33. Reset the Tire Pressure Monitor System. See Tire Pressure Monitor Operation on page 5-62. Make certain that all wheel nuts are properly tightened. See "Wheel Nut Torque" under Capacities and Specifications on page 5-111.
