The Italian tire shop owner in Cars is Luigi.
Luigi is a cheerful 1959 Fiat 500 who owns Luigi’s Casa Della Tires in Radiator Springs. His shop is recognizable for its tall display of tires arranged to resemble the Leaning Tower of Pisa, a visual joke that reflects his Italian identity.
Luigi is one half of an Italian duo with Guido, a small forklift who works at the tire shop. Although Luigi is the talkative enthusiast, Guido is the team’s remarkably fast tire changer. Their shared passion for Scuderia Ferrari becomes especially important when Lightning McQueen arrives in Radiator Springs.
The most common mix-up is Guido: he works with Luigi and is closely associated with tires, but he is not the shop owner. Mario and Tony are not the relevant Cars characters. Luigi’s name also connects to the Italian setting and the film’s affectionate use of automotive and cultural stereotypes.
