Tires
We don’t make 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 bookJet
for details. 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 airout and a serious accident. See
“Loading Your Vehicle”
m the Index.
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.
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.
ProCarManuals.com

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
I mile (I .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.

Don't let anyone tell you that underinflation or
overinflation is
all right. It's not. If your tires
don't have enough air (underinflation), you can
get the following:
NOTICE: (Continued)
NOTICE: (Continued)
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
if your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When
to Check
Check your tires once
a month or more. Also, check the
tire pressure of the spare tire,

How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may
look
properly inflated even when they’re underinflated.
Be sure
to put the valve caps back on the valve
stems. They help prevent leaks
by keeping out dirt
.and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000 km) for any signs of unusual wear. If
unusual wear
is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See “When It’s Time for New
Tires” and ‘‘Wheel Replacement” later
in this section for
more information.
If your vehicle has dual rear wheels,
also see “Dual ‘Tire Operation” later
in this section.

The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals.
If
your vehicle has single rear wheels, always use one of
the correct rotation patterns
shown here when rotating
your tires.
If your vehicle has front [Ires with different load ranges
or tread designs (such as all season vs. on/off road) than
the rear tires, don’t rotate your tires front to rear.
