Operation Tires and wheels i The pressures listed for light loads are minimum values offering high driving comfort. Increased inflation pressures listed for heavier loads may also be used for light loads. These higher pressures produce favorable handling characteristics. The ride of the vehicle, however, will be somewhat harder. Never exceed the max. values or inflate tires below the min. values listed on the fuel filler flap. Tire pressure changes by approximately 1.5 psi (0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind when checking tire pressure where the temperature is different from the outside temperature. Tire temperature and tire pressure also increase while driving, depending on the driving speed and the tire load. Warning! G Follow recommended tire inflation pressures. Do not overinflate tires. Overinflated tires can result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes, etc. Do not underinflate tires. Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overload the tires by exceeding the specified vehicle capacity weight (as indicated by the label on the pillar in the driver's door opening). Overloading the tires can overheat them, possibly causing a blowout. Check the spare tire periodically for condition and inflation pressure. Spare tires will age and become worn over time even if never used, and thus should be inspected and replaced when necessary or after a maximum of six years. 272
