07 Wheels and tires General information NOTE are printed on the side of the tire. When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire should be replaced. Tires with less than 1/16" (1.6 mm) tread offer very poor traction. When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the vehicle. • If the tires are rotated, they should only be moved from front to rear or vice versa. They should never be rotated left to right/right to left. Ideally, tire rotation should be done the first time after approximately 3,000 miles (5,000 km) and thereafter at 6,000-mile (10,000-km) intervals. Some customers find that tire rotation may help to get extra mileage from tire life. Tire rotation should only be performed if front/rear tire wear is fairly even and tread height is above 1/16" (1.6 mm). • • Tread wear indicator 07 The tires have wear indicator strips running across or parallel to the tread.
