DOT plant code 0AT
Source: NHTSA equipment plant codes, last updated November 9, 2026 (UTC).
Example shape: DOT 05H 9T5R 2319. It is not one tire's number. Manufacturers stamp a production week, not a single day, so the age is a range. This site reads that week as Sunday through Saturday under 49 CFR 574.5, not as an ISO week. Nothing you type is stored or sent.

How do I find the date on a tire with plant code 0AT?
The date is the last four digits of the full DOT code on one sidewall: two digits for the week, then two digits for the year. Paste that code in the box above. If this sidewall shows only plant code 0AT, check the other sidewall for the date.

How to find this code on your tire
The plant code is the first group of the tire identification number molded into the sidewall. The letters DOT in front of it are a certification mark, not the plant code. The symbol rules are in 49 CFR 574.5.
On a current new tire the number has 13 symbols: plant code 0AT, then six symbols the manufacturer assigns, then four digits for the week and the year. A retreaded tire's number in 49 CFR 574.5(a)(2) is 7 symbols: the plant code and the four-digit date. This record does not list a former two-symbol code.
49 CFR 574.5 requires the full number on one sidewall. On many radial tires the other sidewall leaves the date off, so the plant code can sit on either side. If you do not see 0AT on the side you can read, check the other sidewall.
