In Pixar's Cars, which race ends in a three-way tie for the Piston Cup?

In Pixar's Cars, the Dinoco 400 ends in a three-way tie for the Piston Cup.

The race takes place at the Motor Speedway of the South and appears to settle the season's championship. A tire failure for Lightning McQueen, a crash involving Chick Hicks, and The King's trouble in the closing laps create the unusual result. Officials then schedule a tiebreaker at the Los Angeles International Speedway.

The three tied racers are McQueen, Hicks, and The King. McQueen's decision during the tiebreaker changes the emotional meaning of the championship and leads to the film's final resolution rather than a simple victory celebration.

The Dinoco 400 is not the tiebreaker itself. The title race is the later event, while the Dinoco 400 is the competition that produces the tie. This distinction matters because the film includes several named Piston Cup races.
