Tires - GMC Sierra 2005 Owner's Manual

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 4-50.
•
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 5-76.

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.
20-Inch Tires
If your vehicle has the optional 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 with Your Four-Wheel-Drive Vehicle on
page 4-19 and Adding a Snow Plow or Similar
Equipment on page 4-56 for additional information.
