Tires

Every new GM vehicle has high-quality tires made by a leading tire manufacturer. See the warranty manual for information regarding the tire warranty and where to get service. For additional information refer to the tire manufacturer.

WARNING
• Poorly maintained and improperly used tires are dangerous.
• Overloading the tires can cause overheating as a result of too much flexing. There could be a blowout and a serious crash. See Vehicle Load Limits on page 9‑17.
• Underinflated tires pose the same danger as overloaded tires. The resulting crash could cause serious injury.
Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when the tires are cold.
• Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact — such as when hitting a pothole. Keep tires at the recommended pressure.
• Worn or old tires can cause a crash. If the tread is badly worn, replace them.
• Replace any tires that have been damaged by impacts with potholes, curbs, etc.
• Improperly repaired tires can cause a crash. Only the dealer or an authorized tire service center should repair, replace, dismount, and mount the tires.
• Do not spin the tires in excess of 55 km/h (35 mph) on slippery surfaces such as snow, mud, ice, etc. Excessive spinning may cause the tires to explode.

See Tire Pressure for High-Speed Operation on page 10‑63 for inflation pressure adjustment for high speed driving.

20-Inch Tires

If the vehicle has 20-inch P275/ 55R20 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 or commercial uses such as snow plowing. See Off-Road Driving on page 9‑6 and Adding a Snow Plow or Similar Equipment on page 9‑113 for additional information.

Notice: 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. The 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.
