CAUTION: (Continued) D Overinflated tires are more likely to be cut, punctured or broken by a sudden impact -- such as when you hit a pothole. Keep tires at the recommended pressure. D Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them. See "Inflation -- Tire Pressure" in this section for inflation pressure adjustment for higher speed driving. 235/45R17. When you end this very high-speed driving, reduce the cold inflation pressures to those listed on the Tire-Loading Information label. NOTICE: Don't let anyone tell you that underinflation or overinflation is all right. It's not. If your tires don't have enough air (underinflation), you can get the following: D Too much flexing D Too much heat D Tire overloading D Bad wear D Bad handling D Bad fuel economy. If your tires have too much air (overinflation), you can get the following: D Unusual wear D Bad handling D Rough ride D Needless damage from road hazards. Inflation -- Tire Pressure The Tire-Loading Information label, which is located on the rear edge of the driver's door, shows the correct inflation pressures for your tires when they're cold. "Cold" means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). If you'll be driving at speeds higher than 100 mph (160 km/h) where it is legal, raise the cold inflation pressure of each tire to 38 psi (260 kPa) for tire size P225/55R16 and to 39 psi (270 kPa) for tire size 6-39
