"Luigi runs the local tire shop in Radiator Springs, Luigi's Casa Della Tires. If you're gonna be driving through this world, why not look good doing it? That's Luigi's motto. Cars may not get to choose their body type, but they all have a choice when it comes to the tires they wear. 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.
