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 on page 9 10.
WARNING (Continued)
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
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.
