You need new tires if any of the following statements
are true:
.
You can see the indicators at three or more places
around the tire.
.
You can see cord or fabric showing through the
tire's rubber.
.
The tread or sidewall is cracked, cut, or snagged
deep enough to show cord or fabric.
.
The tire has a bump, bulge, or split.
.
The tire has a puncture, cut, or other damage that
cannot be repaired well because of the size or
location of the damage.
The rubber in tires degrades over time, even if they
are not being used. This is also true for the spare tire,
if your vehicle has one. Multiple conditions affect how
fast this aging takes place, including temperatures,
loading conditions, and inflation pressure maintenance.
With proper care and maintenance tires will typically
wear out before they degrade due to age. If you are
unsure about the need to replace your tires as they get
older, consult the tire manufacturer for more information.
Buying New Tires
GM has developed and matched specific tires for
your vehicle. The original equipment tires installed
on your vehicle, when it was new, were designed
to meet General Motors Tire Performance Criteria
Specification (TPC Spec) system rating. If you
need replacement tires, GM strongly recommends
that you get tires with the same TPC Spec rating.
This way, your vehicle will continue to have tires
that are designed to give the same performance
and vehicle safety, during normal use, as the
original tires.
GM's exclusive TPC Spec system considers over
a dozen critical specifications that impact the
overall performance of your vehicle, including
brake system performance , ride and handling,
traction control, and tire pressure monitoring
performance. GM's TPC Spec number is molded
onto the tire's sidewall near the tire size. If the
tires have an allseason tread design, the TPC
Spec number will be followed by an MS for
mud and snow. See Tire Sidewall Labeling
