Until just recently there are NO ST tires that are produced in the USA. Last month Goodyear announced their new ST tire, the Endurance and said that it will be produced in the US.

To my knowledge, this is the only ST tire manufactured in the US. I haven't heard of any reports on durability, reliability or performance. It's available at Tire Rack, Wal Mart and other tire sales centers.
