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 395 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.
Your vehicle may have a compact spare
tire and wheel assembly. If the vehicle has
a compact spare tire and wheel, they have
the same overall diameter as your vehicle’s
full-size tires and wheels. Because they
were designed and developed for use on
your vehicle, it is all right to drive your
vehicle with the compact spare installed
properly. Compact spare tires are designed
for temporary use only. See
Spare Tire
on page 430 .
