230 Tires and wheels Recommended tire inflation pressure G Warning! Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure. pressure. Otherwise, the tire will be underinflated. Follow recommended cold tire inflation pressures listed on Tire and Loading Information placard on the driver's door B-pillar. Keeping the tires properly inflated provides the best handling, tread life and riding comfort. In addition to the Tire and Loading Information placard on the driver's door B-pillar, also consult the tire inflation pressure label on the inside of the filler flap for any additional information pertaining to special driving situations. For more information, see "Important notes on tire inflation pressure" (Y page 231). Operation Your vehicle is equipped with the Tire and Loading Information placard located on the driver's door B-pillar (Y page 238). The tire inflation pressure should be checked regularly. Only adjust the tire inflation pressure on cold tires. The tires can be considered cold if the vehicle has been parked for at least 3 hours or driven less than 1 mile (1.6 km). Depending on the ambient temperature, the driving speed and the tire load, the tire temperature changes. When the tire temperature changes by 18‡ (10†), the tire inflation pressure will change by approximately 1.5 psi (0.1 bar). Keep this in mind when checking tire inflation pressure on warm tires and adjust the tire pressure only if the tire inflation pressure is too low for the current operating conditions. If you check the tire inflation pressure when the tires are warm, the reading will be higher than the cold reading. This is normal. Do not let air out to match the specified cold tire inflation i Data shown on Tire and Loading Information placard example are for illustration purposes only. Tire data are specific to each vehicle and may vary from data shown in the following illustration. Refer to Tire and Loading Information placard on vehicle for actual data specific to your vehicle. The Tire and Loading Information placard lists the recommended cold tire inflation pressures : for maximum loaded vehicle weight. The tire inflation pressures listed apply to the tires installed as original equipment.
