Any GM new vehicle sold in the United States or Canada today comes with high-quality tires made by a leading tire manufacturer. If you have questions about your warranty coverage, or where to obtain service, see your vehicle's owner's manual or warranty folder for details. Also, see your owner's manual for information about vehicle loading. Overloading your 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 tires are cold. Overinflated tires are more likely to give a harsh ride and exhibit rapid tread wear at the center of the tire. Keep tires at the recommended pressure.
