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 423 for additional information.
The optional 18-inch performance tires, size
255/45ZR18 99Y, used on some vehicles, meet
the General Motors Tire Performance Criteria
Specification (TPC Spec) rating but the TPC Spec
code has not been molded onto the tire’s
sidewall. If your vehicle has these tires, and you
need to replace them, you can still get these TPC
Spec rated tires by asking your GM dealer.
Your GM dealer can order these tires by part
number. This way, your vehicle will continue to
give the proper endurance, handling, traction, and
ride as the original tires.
