Unbalanced wheels impair tire economy and driving comfort. Tires must maintain the same direction of rotation throughout their lifetime. When replacing tires, the tires with the most tread should be mounted on the rear wheels to reduce the chance of oversteer during hard braking. Hitting curbs or potholes can damage the tires and/or wheels permanently. 247 06 Maintenance and specifications Wheels and tires Tire inflation Tire inflation Check tire inflation pressure regularly. Tables listing the recommended inflation pressure for your vehicle can be found on pages 250 and 251. A tire inflation pressure placard is also located on the driver's side Bpillar (the structural member at the side of the vehicle, at the rear of the driver's door opening). This placard indicates the designation of the factory-mounted tires on your vehicle, as well as load limits and inflation pressure. NOTE The placards shown indicate inflation pressure for the tires installed on the vehicle at the factory only. A certain amount of air seepage from the tires occurs naturally and tire pressure fluctuates with seasonal changes in temperature. Always check tire pressure regularly. Use a tire gauge to check the tire inflation pressure, including the spare, at least once a month and before long trips. You are strongly urged to buy a reliable tire pressure gauge, as automatic service station gauges may be inaccurate. Use the recommended cold inflation pressure for optimum tire performance and wear. Under-inflation or over-inflation may cause uneven treadwear patterns. WARNING Under-inflation is the most common cause of tire failure and may result in severe tire cracking, tread separation, or "blowout," with unexpected loss of vehicle control and increased risk of injury. Under-inflated tires reduce the load carrying capacity of your vehicle.
