High Speed Operation (Red Line) 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 5-68 and Wheel Replacement on page 5-72 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. {CAUTION: Driving at high speeds, 100 mph (160 km/h) or higher, puts an additional strain on tires. Sustained high-speed driving causes excessive heat build up and can cause sudden tire failure. You could have a crash and you or others could be killed. Some high-speed rated tires require inflation pressure adjustment for high speed operation. When speed limits and road conditions are such that a vehicle can be driven at high speeds, make sure the tires are rated for high speed operation, in excellent condition, and set to the correct cold tire inflation pressure for the vehicle load. If your vehicle has 215/45ZR17 size tires, set the cold tire inflation pressure to 33 psi (227 kPa) for the front and rear tires when operating your vehicle under high-speed conditions. When you end high-speed driving, return the tires to the cold inflation pressure shown on the tire and loading information label. Non-Directional Tires When rotating non-directional tires, always use the correct rotation pattern shown here. 5-66
