Buying New Tires - Chevrolet 2007 Colorado Owner's Manual

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 by the tire manufacturer.
If the tires have an all-season tread design,
the TPC spec number will be followed by an MS
for mud and snow. See Tire Sidewall Labeling
on page 378 for additional information.

CAUTION:
{
Mixing tires could cause you to lose
control of your vehicle while driving.
If you mix tires of different sizes, brands,
or types (radial and bias-belted tires),
the vehicle may not handle properly, and
you could have a crash. Using tires of
different sizes, brands, or types may also
cause damage to your vehicle. Be sure
to use the correct size, brand, and type
of tires on all wheels.
