The U.S. Department of Transportation requires all tires sold in the U.S. to carry a code indicating the company and plant where they were manufactured.

The code looks like this: DOT BE XX XXX XXX.  The Xs stand for numbers and/or letters that are not part of the plant ID code.  The two letters or letter and number that follow DOT indicate the company and plant where the tire was manufactured.  In this example, the BE indicates the tire was made by B.F. Goodrich in Tuscaloosa, AL.

Here is a current listing of U.S. unionized tire DOT codes.  Compare this list with the code on any tire you are considering buying to be certain you are getting a union-made (United Steelworkers - USW) tire made in North America.
