Tire Sidewall Labeling
Useful information about a tire is molded into its
sidewall. The examples below show a typical
passenger vehicle tire and a compact spare tire
sidewall.(A) Tire Size
:The tire size is a combination of
letters and numbers used to de ne a particular
tire’s width, height, aspect ratio, construction type
and service description. See the “Tire Size”
illustration later in this section for more detail.
(B) TPC Spec (Tire Performance Criteria
Speci cation)
:Original equipment tires designed
to GM’s speci c tire performance criteria have a
TPC speci cation code molded onto the sidewall.
GM’s TPC speci cations meet or exceed all federal
safety guidelines. If your vehicle has 205/55R16
size tires, they meet the GM TPC Spec rating, but
the TPC Spec code has not been molded onto the
tire’s sidewall.
(C) DOT (Department of Transportation)
:The Department of Transportation (DOT) code
indicates that the tire is in compliance with the
U.S. Department of Transportation Motor Vehicle
Safety Standards.
