when possible, avoid contact with
curbs, potholes, and other road
hazards.

Tire Sidewall Labeling

Useful information about a tire is
molded into its sidewall. The
examples show a typical
passenger vehicle tire and a
compact spare tire sidewall.

Passenger (P-Metric) Tire Example

(1) Tire Size

:

The tire size 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.

(2) 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.

(3) 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.

DOT Tire Date of
Manufacture

:

The last four

digits of the TIN indicate the tire
manufactured date. The first two
digits represent the week
(01

52) and the last two digits,

the year. For example, the third
week of the year 2010 would
have a four-digit DOT date
of 0310.

(4) Tire Identification Number
(TIN)

:

The letters and numbers

following the DOT (Department
of Transportation) 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.

(5) Tire Ply Material

:

The type

of cord and number of plies in
the sidewall and under the tread.
