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.

Passenger (P-Metric) Tire Example

(B)TPC Spec (Tire Performance Criteria Specification): Original equipment tires designed to GM’s specific tire performance criteria have

a TPC specification code molded onto the sidewall. GM’s TPC specifications meet or exceed all federal safety guidelines.
