My BFG T/A' were made in the US, the Nitto's in Japan. BFG is apparently owned by Michelin, Nitto by Toyo. I suspect DB uses a variety of new tires, and undoubtedly some are price point driven.
I don't know how current or accurate this is, but scrolling down you'll find the brands/plant locations for US made tires. They might be foreign companies (like Michelin) but maybe you can find a DB or an other aftermarket source that does whitewalls from an American plant.
