Tire Inspection We recommend that you regularly inspect your vehicle's tires, including the spare tire, if the vehicle has one, for signs of wear or damage. See When It Is Time for New Tires on page 9‑58 for more information. Tire Rotation Tires should be rotated every 8 000 to 13 000 km (5,000 to 8,000 miles). See Scheduled Maintenance on page 10‑2 . The purpose of a regular tire rotation is to achieve a uniform wear for all tires on the vehicle. This will ensure that the vehicle continues to perform most like it did when the tires were new.
