In Pixar's Cars, what is Mater's full name or vehicle-based name?

Mater's vehicle-based name in Pixar's Cars is Tow Mater.

The name is a pun on the phrase tow mater, reflecting Mater's role as Radiator Springs' rusty tow truck. He introduces himself as a best friend to Lightning McQueen and becomes one of the film's most recognizable characters. The character is voiced by Larry the Cable Guy in the English-language films.

Mater's design is a 1951 International Harvester boom truck combined with features associated with a 1957 Chevrolet Task-Force pickup. In the films, characters commonly call him simply Mater, so some references list that shorter name. Tow Mater is the canonical full character name used in character and franchise materials, while the spelling is intentionally based on the pronunciation of tomato.
