Tyre DOT Decoder

The US Department of Transportation established a requirement in January 1971 for a tire identification number (TIN) that must be labeled on one sidewall of each tire that is newly manufactured or retreaded. (to be sold in the U.S market)
The length of the TIN was standardized to 13 symbols for new tires and 7 symbols for retreaded tires in April 2015.

Locate the DOT code

If you cannot find the text "DOT" at the sidewall, it will be located on the inside sidewall. The first two digits of the TIN indicate the manufacturer’s plant code, while the remaining digits indicate the tire size and date of manufacture.

Check the manufacturing date

The last four digits represent the week and year of manufacture. For example, '2319' means the 23rd week of 2019.

Even though the code is mandated by the US Department of transport, it is used worldwide. Therefore the DOT code applies to all tires manufacturered for use on public roads, regardless of the market they are sold in. If the DOT code is not imprinted on the sidewall, it does not mean the tire is not authorized to be sold or a counterfeited product. It just mean the batch of tire is not sold to the market that requires the DOT by law.
The list is for reference. Please refer to the U.S. Department of Transport for the latest update on the tyre DOT, especially on the status of the plant.

Frequently Asked Questions

1. How to find manufacture place of a tire using DOT?
DOT is imprinted on both tire sidewalls. If you cannot find "DOT" text on it, you can try looking for a string of letters and/or numbers. Normally it contains 4-5 letters and/or numbers. Take the first 2 or 3 characters, and input it on the above search field to see if it output any results.

2. What is the maximum age for a tire?
10 years maximum since production of the tire. Suggest to get inspected by technician from 6 years onwards to determine the tire usability.

According to various factory recommendation such as Michelin, Continental, Bridgestone, advise drivers to get your tire replaced 10 years starting from the prodction of the tire.

3. How old should my new tires be?
