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.
CAUTION:
Poorly maintained and improperly used tires
are dangerous.
D 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” in the Index.
D 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.
CAUTION: (Continued)
CAUTION: (Continued)
D 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.
D Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
Inflation -- Tire Pressure
The Certification/Tire label, which is on the rear edge of
the driver’s door, or on the incomplete vehicle document
in the cab, shows the correct inflation pressures for your
tires when they’re cold. “Cold” means your vehicle has
been sitting for at least three hours or driven no more
than 1 mile (1.6 km).
You can operate some vehicles at reduced inflation
pressures only when you’ll be carrying reduced loads. On
those vehicles, the minimum cold inflation pressures for a
typical reduced load are printed on the Improved Ride Tire
Pressure label located on the driver’s door. Weigh the
vehicle to find the load on each tire and see the label for
the minimum cold inflation pressures for that load.
