Vehicle Care

9-61

The rubber in tires degrades over
time. This is also true for the spare
tire, if the vehicle has one, even if it
is not being used. Multiple
conditions affect how fast this aging
takes place, including temperatures,
loading conditions, and inflation
pressure maintenance. With proper
care and maintenance tires typically
wear out before they degrade due to
age. If you are unsure about the
need to replace the 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 all-season tread
design, the TPC Spec number
will be followed by an MS for
mud and snow. See
