Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your vehicle Warranty booklet for details. CAUTION: (Continued) • 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. • Worn, old tires can cause accidents. If the tire's tread is badly worn, or if your vehicle's tires have been damaged, replace them. {CAUTION: Poorly maintained and improperly used tires are dangerous. • Overloading your vehicle's tires can cause overheating as a result of too much flexing. You could have an air-out and a serious accident. See Loading Your Vehicle on page 4-36. • Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your vehicle's tires are cold. See Inflation - Tire Pressure on page 5-76. CAUTION: (Continued) 20-Inch Tires If your vehicle has the optional 20-inch P275/55R20 size tires, they are classified as touring tires and are designed for on road use. The low-profile, wide tread design is not recommended for "off-road" driving or commercial uses such as snow plowing. See Off-Road Driving on page 4-12 and Adding a Snow Plow or Similar Equipment on page 4-43 for additional information. 5-68
