Tire Identification Number (TIN)
Tire Identification Number (TIN) is marked on the intended outboard sidewall. The TIN is composed of four groups. Here is a brief review of the TIN with a breakdown of its individual elements.

(1) Manufacturer’s Identification Mark
(2) Tire Size
(3) Tire Type Code
(4) Date of Manufacture
The first two figures identify the week, starting with “01” to represent the first full week of the calendar year; the second two figures represent the year. For example, 0101 means the 1st week of 2001.
