Tire Sidewall Labeling

Useful information about a tire is molded into the

sidewall. The following illustrations are examples

of a typical P-Metric and a LT-Metric tire sidewall.

(A) Tire Size

: The tire size code is a combination

of letters and numbers used to deﬁne 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

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.

The Department of Transportation (DOT) code

indicates that the tire is in compliance with the U.S.

Department of Transportation Motor Vehicle Safety

Standards.

(D) Tire Identiﬁcation Number (TIN)

: The letters

and numbers following DOT code are the Tire

Identiﬁcation Number (TIN). The TIN shows the

manufacturer and plant code, tire size, and date the

tire was manufactured. The TIN is molded onto both

sides of the tire, although only one side may have

the date of manufacture.

(E) Tire Ply Material

: The type of cord and number

of plies in the sidewall and under the tread.

(F) Uniform Tire Quality Grading (UTQG)

: Tire

manufacturers are required to grade tires based on

three performance factors: treadwear, traction, and

temperature resistance. For more information, see

Uniform Tire Quality Grading on page 5-86.
