07 Wheels and tires General information NOTE Tread wear indicator • 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). G020323 • • Your Volvo retailer can also provide guidance based on your particular driving circumstances. The tires have wear indicator strips running across or parallel to the tread. The letters TWI 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. 07 180
