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

CAUTION:
Poorly maintained and improperly used tires are dangerous.

• Overloading your vehicle’s tires can cause overheating as a result of too much friction. You could have an air-out and a serious accident.
• 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.
