What is the title of Pixar's short-film series centered on Mater?

Pixar's short-film series centered on Mater is titled Mater's Tall Tales.

The series features Mater recounting extraordinary stories about his supposed past adventures. Lightning McQueen usually listens as Mater describes experiences involving racing, espionage, rescue work, or other spectacular events. The humor comes from Mater's confidence and the question of how literally his stories should be taken.

Mater's Tall Tales debuted in 2008 as part of the Cars Toons collection. The shorts expanded the franchise beyond the three feature films and gave Mater a larger role as the central storyteller. Several episodes pair him with Lightning or place him in settings unrelated to the main Radiator Springs plot.

The title is sometimes confused with Cars Toons, which is the broader branding used for animated shorts based on the Cars franchise. Mater's Tall Tales is the specific Mater-led series. The franchise also includes other shorts, including Tales from Radiator Springs, so the exact series name matters.
