What is the title of Pixar's Cars short-film series that began in 2008?

The Pixar Cars short-film series that began in 2008 is titled Cars Toons: Mater's Tall Tales.

The series debuted on October 27, 2008, with the short “Rescue Squad Mater.” Its stories center on Mater telling increasingly elaborate tales about his supposed past adventures, while Lightning McQueen often appears as an audience or participant.

The shorts deliberately blur the line between Mater's storytelling and reality. Their comic episodes place him in roles such as a firefighter, a stunt performer, and a time-traveling character, giving the franchise a lighter format than the feature films.

The collection was originally known as Mater's Tall Tales and was later branded Cars Toons. It should not be confused with Cars on the Road, a separate Disney+ series released in 2022 with nine episodes.
