Wheels and Tires

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 0 217.
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.
