GM Service Manual Online
For 1990-2009 cars only

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. For additional information refer to the tire manufacturer.

Caution: 

   • Poorly maintained and improperly used tires are dangerous.
   • Overloading your tires can cause overheating as a result of too much flexing. You could have an air-out and a serious accident. See Loading the Vehicle .
   • 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 tires are cold. See Inflation - Tire Pressure .
   • 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 your tread is badly worn, or if your tires have been damaged, replace them.
See High-Speed Operation for inflation pressure adjustment for high speed driving.

22-Inch Tires

If your vehicle has the optional 22-inch P285/45R22 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. See Off-Road Driving , for additional information.
