TIRE CHAINS Use of tire chains may be prohibited according to location. Check the local laws before installing tire chains. When installing tire chains, make sure they are the proper size for the tires on your vehicle and are installed according to the chain manufacturer's suggestions. Use only SAE Class S chains. Class "S" chains are used on vehicles with restricted tire to vehicle clearance. Vehicles that can use Class "S" chains are designed to meet the SAE standard minimum clearances between the tire and the closest vehicle suspension or body component required to accommodate the use of a winter traction device (tire chains or cables). The minimum clearances are determined using the factory equipped tire size. Other types may damage your vehicle. Use chain tensioners when recommended by the tire chain manufacturer to ensure a tight fit. Loose end links of the tire chain must be secured or removed to prevent the possibility of whipping action damage to the fenders or underbody. If possible, avoid fully loading your vehicle when using tire chains. In addition, drive at a reduced speed. Otherwise, your vehicle may be damaged and/or vehicle handling and performance may be adversely affected. Tire chains must be installed only on the rear wheels and not on the front wheels. Never install tire chains on a TEMPORARY USE ONLY spare tire. Do not use tire chains on dry roads. Driving with tire chains in such conditions can cause damage to the various mechanisms of the vehicle due to some overstress. SDI1662 CHANGING WHEELS AND TIRES Tire rotation (Models equipped with same size tires on all wheels) INFINITI recommends rotating the tires every 7,500 miles (12,000 km). (See "FLAT TIRE" in the "6. In case of emergency" section for tire replacing procedures.) As soon as possible, tighten the wheel nuts to the specified torque with a torque wrench. Maintenance and do-it-yourself 8-37
