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 0 179.
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.
Improperly repaired tires can cause
a crash. Only your dealer or an
authorized tire service center
should repair, replace, dismount,
and mount the tires.
(Continued)
Do not spin the tires in excess of
56 km/h (35 mph) on slippery
surfaces such as snow, mud, ice,
etc. Excessive spinning may cause
the tires to explode.

Winter Tires

This vehicle was not originally equipped
with winter tires. Winter tires are designed
for increased traction on snow and
such as when
ice-covered roads. Consider installing winter
tires on the vehicle if frequent driving on ice
or snow covered roads is expected. See your
dealer for details regarding winter tire
availability and proper tire selection. Also,
see Buying New Tires 0 331.
With winter tires, there may be decreased
dry road traction, increased road noise, and
shorter tread life. After changing to winter
tires, be alert for changes in vehicle
handling and braking.
If using winter tires:
Use tires of the same brand and tread
type on all four wheel positions.
