Lightning McQueen: "I love being me."
- —Mia and Tia meeting their hero Lightning McQueen
Mia and Tia are characters in Cars.
"Mia and Tia haven't missed a race in over a year, but they'd be the first to tell you they're not race fans, they're Lightning McQueen fans! Painted in his signature red and covered in McQueen stickers, the girls scream like crazy when McQueen races, they scream like crazy when he poses for photos, and they scream like crazy all the way home just thinking about him."
"McQueen's many daydreams of success have him seeing double, as Dinoco blue is not only in his future, but also in the future of his two biggest fans, Mia and Tia. After all, they follow him wherever he's headed, and in his mind he's headed for the biggest sponsorship around."
"Lightning McQueen's dreams of success are humble, really. Well, maybe at first -- but gone unchecked the houses get bigger, the fame more powerful and the lifestyle flashier. In his vision of the future everything is gold plated: his rims, his teeth and of course...his favorite fans!"
"With Lightning McQueen missing in action his two biggest fans Mia and Tia were devastated, and that is when Chick Hicks swooped in to console them, loading them up with his own merchandise and a free Hostile Takeover Bank sponsored paint job. Mia and Tia begrudgingly accepted the offer, not because they're Chick Hicks fans, but because the color green complimented their eyes."
"Now that Flo's V-8 Cafe is the watering hole for the who's who of the racing circuit, Mia and Tia have moved to town and quickly become Flo's most popular waitresses. After all, what better way to be close to their hero Lightning McQueen!"
Mia and Tia, often refered to as "The Twins", are identical twin Mazda Miata sisters who are Lightning McQueen's self-proclaimed biggest fans. They are, however, quite fickle; after McQueen's disappearance, the twins suddenly become ardent fans of Chick Hicks. By the end of the movie, they are McQueen's fans once more, turning against Hicks after he deliberately caused The King to crash in the tie-breaker race. With McQueen, Mia and Tia eventually move to Radiator Springs, where they work as waitresses at Flo's V8 Cafe, as seen during the end credits. In a deleted scene on the Cars DVD, the twins were waitresses at Top Down Truck Stop that McQueen stopped at.

Cars Toons: Mater's Tall Tales
The twins appear in all the Cars Toons shorts (except Time Travel Mater, possibly due to the fact that they are modern cars and would be anachronistic if present), where they are usually depicted as being fans of Mater. While they are generally only background characters, in Mater Private Eye, they are major characters, to such an extent that both have a different role in the story.
