Warning
.
Poorly maintained and improperly
used tires are dangerous.
.
Overloading the tires can cause
overheating as a result of too
much flexing. There could be a
blowout and a serious crash. See
Vehicle Load Limits 0 77.
.
Underinflated tires pose the same
danger as overloaded tires. The
resulting crash could cause serious
injury. Check all tires frequently to
maintain the recommended
pressure. Tire pressure should be
checked when the tires are cold.
.
Overinflated tires are more likely
to be cut, punctured, or broken by
a sudden impact — such as when
hitting a pothole. Keep tires at the
recommended pressure.
.
Worn or old tires can cause a
crash. If the tread is badly worn,
replace them.

Warning (Continued)
.
Replace any tires that have been
damaged by impacts with
potholes, curbs, etc.
.
Improperly repaired tires can cause
a crash. Only your dealer or an
authorized tire service center
should repair, replace, dismount,
and mount the tires.
.
Do not spin the tires in excess of
56 km/h (35 mph) on slippery
surfaces such as snow, mud, ice,
etc. Excessive spinning may cause
the tires to explode.

Tire Sidewall Labeling
Useful information about a tire is
molded into the sidewall. The example
shows a typical passenger vehicle tire
sidewall.
Passenger/Spare Tire
(1) Tire Size : The tire size is a
combination of letters and numbers
used to define a particular tire's width,
height, aspect ratio, construction type,
and service description. See the "Tire
Size" illustration in this section.
(2) TPC Spec (Tire Performance Criteria
Specification)
: Original equipment tires
designed to GM's specific tire
performance criteria have a TPC
specification code molded onto the
sidewall. GM's TPC specifications meet
or exceed all federal safety guidelines.
