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 GM Warranty booklet for details. For additional information refer to the tire manufacturer's booklet included with your vehicle's Owner Manual.

CautionPoorly 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 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 vehicle's 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 the tire's tread is badly worn, or if your vehicle's tires have been damaged, replace them.

Notice: If your vehicle has P245/45R18 size tires, they are classified as low-profile tires. Low-profile tires are more susceptible to damage from road hazards or curb impact than standard profile tires. Tire and or wheel assembly damage can occur when coming into contact with road hazards like, potholes or sharp edged objects or when sliding into a curb. Your GM warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and when possible avoid contact with curbs, potholes and other road hazards.

Winter Tires

If you expect to drive on snow or ice covered roads often, you may want to get winter tires for your vehicle. All season tires provide good overall performance on most surfaces but they may not offer the traction you would like or the same level of performance as winter tires on snow or ice covered roads.

See your dealer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires .

If you choose to use snow tires:

    • Use tires of the same brand and tread type on all four wheel positions.
    • Use only radial ply tires of the same size, load range, and speed rating as the original equipment tires.

Winter tires with the same speed rating as your original equipment tires may not be available for H, V, W and ZR speed rated tires. If you choose snow tires with a lower speed rating, never exceed the tire's maximum speed capability.
