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.

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.

Low-Profile Tires (XLR-V)

Notice: If your vehicle has P235/45R19 or P255/40R19 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 (XLR-V)

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.

Winter tires, in general, are designed for increased traction on snow and ice covered roads. With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After switching to winter tires, be alert for changes in vehicle handling and braking.

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

If you choose to use winter 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, Y, and ZR speed rated tires. If you choose winter tires with a lower speed rating, never exceed the tire's maximum speed capability.
