Continuity mistake: In the tractor tipping scene, Mater demonstrates to McQueen how to do it using two tractors before Mcqueen's first try. And then when McQueen accelerates to make the noise and we have a wide open shot of the field, we can see that all the tractors in the field are still turning. Missing are the two already done by Mater. (00:55:40 - 00:56:25)
Continuity mistake: Before Lightning falls off the end of Mack's trailer, you can see Snot Rod and one of the other cars running alongside the trailer. But when the camera moves to show Lightning coming off the trailer, you can see alongside the trailer in the background, and the cars are now missing. Camera switches back to the front of Mack, and the cars are back alongside again.GalahadFairlight
Continuity mistake: After the first race, McQueen blew out both back tires. When interviewed after the race, his pit crew changes his rims with new tires, but the old rims have tires on them. They should be only rims, since earlier in the race we see him riding "on the rims" only, with sparks flying from the metal touching the track.
Continuity mistake: When McQueen rides on the wall to pass Rusty Cornfuel and Floyd Mulvihill, he passes Winford Bradford Rutherford and Sage VanDerSpin and goes straight to Slider Petrolski. However, past him are Todd Marcus, Ernie Gearson, and Winford Bradford Rutherford again, making it look as if there were two RPM cars with the same exact body, but there aren't.Paul Thomas Backes
Continuity mistake: McQueen kicks a can into Doc's slightly-open garage door. The door opens outward. McQueen then slowly pushes both garage doors inward to open them, opposite of how the door was just shown. When Doc subsequently throws McQueen out of the garage he slams the door shut...which would not be possible if it swung in both directions.Kit Sullivan
