The U.S. Department of Transportation (DOT) has made it very easy to find union-made tires by requiring that each tire carry a code that shows the company and the location of the plant that manufactured the tire. DOT requires that each tire sold in the United States carry a code that looks something like this: DOT BE XX XXX XXX.
