I have been buying Cooper made tires for years (either Cooper, Mastercraft, or ProComp)
Cooper and Good Year are the last USA owned companies making passenger tires in the USA, all other tires made in the USA are from foreign owned companies. After this Good Year (or after this should it be called Bad Year) wont even get consideration.
Bridgestone/Firestone-Japan
Michelin-France
Pirelli- China
Toyo-Japan
Continental- Germany
