Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your GM Warranty booklet for details. For additional
information refer to the tire manufacturer’s booklet
included with your vehicle’s Owner’s Manual.

CAUTION:
Poorly maintained and improperly used tires
are dangerous.
•
Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out and a
serious accident. See Loading Your
Vehicle on page 4-42.
•
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. See
Inflation - Tire Pressure on page 5-61.
CAUTION: (Continued)
CAUTION: (Continued)
•
Overinflated tires are more likely to be cut,
punctured, or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
•
Worn, old tires can cause accidents.
If your tread is badly worn, or if your tires
have been damaged, replace them.
