While Cooper and Goodyear are the only remaining American-owned tire companies, some of their products are made outside the country. Additionally, some foreign-owned tire manufacturers have manufacturing plants in the United States.
In order to determine where a manufacturer had produced a particular tire, the consumer should check the U.S. Department of Transportation code that the manufacturer stamps on the tire. The code is in the form DOT XX XX XXX XXX with the first two letters after DOT indicating the manufacturing plant. The letters "BE" represent the BF Goodrich plant from Birmingham, Alabama, while "UT" indicates a Cooper tire from Texarkana, Arkansas.
Goodyear is an international company with American roots. It manufactures most of its tires in the plants it owns in seven different states across the United States. The international company maintains its headquarters in Akron, Ohio and also owns the Dunlop and Kelly Springfield brands. Cooper manufactures tires in Ohio and Georgia.
Several international companies with headquarters outside the United States maintain manufacturing plants within the country. Bridgestone, which purchased Firestone in 1998, has plants in Tennessee, Illinois, Ohio, North Carolina and South Carolina. Michelin, a French company, manufactures tires in Alabama, Arkansas, North Carolina and South Carolina.
