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 Pontiac Warranty booklet for details.
. -orly mai __ and impropel 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” in 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.
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.
Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
inside of the trunk lid, 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).
Notice: 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:
Too much flexing
Too much heat
Tire overloading

10. Don’t try to put the wheel cover on your compact
spare tire. It won’t fit. Store the wheel cover in the
trunk until you have the flat tire repaired or
replaced.
Notice: Wheei covers won’t fit on your compact
spare.
If you try to put a wheel cover on your
compact spare, you could damage the cover or
the spare.
Storing the Flat Tire and Tools
Storing a jack, a tire, or other equipment in the
passenger compartment
of the vehicle could
cause injury.
In a sudden stop or collision,
loose equipment could strike someone.
Store all these
in the proper place.
After you’ve put the compact spare tire on your vehicle,
you’ll need to store the flat tire in the trunk. Use the
following procedure to secure the flat tire in the trunk. When
storing a full-size tire, you must use the extension
to help avoid wheel surface damage. Use the extension
and protector/guide located in the foam holder.
To store a
full-size tire, place the tire in the trunk valve stem facing
down, with the protector/guide placed through a wheel
bolt hole. Remove the protector and attach the retainer
securely. When putting the compact spare back in the
trunk, place the protector/guide back
in the foam holder.
Store the cover as far forward as possible.
