Luigi offers the finest selection of tires west of the Mississippi, and Luigi's Casa Della Tires is known far and wide for its impeccable service, competitive prices, and of course, its very stylish proprietor.
Luigi is a huge fan of Ferrari Racing and is so happy when Ferrari Racer Michael Schumacher shows up at his shop wanting tires in the end.
