Piston Cup race car
Tim Treadless is a next-generation Piston Cup racer who is sponsored by Nitroade. His racing number is 28. He replaced Phil Tankson as one of the first seven next-gen racers along with Jackson Storm, who was the first next-gen and the car that also made a huge impact on the Piston Cup by triggering a new generation, H.J. Hollis, Ryan Laney, Ed Truncan, Aaron Clocker, and Harvey Rodcap.
In Cars 3, Tim competes in the Piston Cup Racing Series's 2016 season. He debuts at the Motor Speedway of the South, replacing Phil Tankson as the Nitroade racer and proven to be a worthy opponent. He finishes in 10th at Grandol Oil Co. Raceway and 4th at Georgia Motor Speedway. He is driving right behind Lightning McQueen when McQueen crashes, and he watches McQueen in shock when he crashes. He finished in fourth, behind racers Daniel Swervez and Chase Racelott as well as first-place winner Jackson Storm.
When a wreck is caused during the Florida 500, Tim is involved in the wreck and is seen colliding with Cam Spinner, then being piled into by a miscolored Ryan "Inside" Laney. He is badly damaged and does not finish the race.
- Due to the fact that IGNTR sells products that are meant to boost a car, Nitroade is likely competing with the aformentioned company, which is likely the reason that Tim appeared inmediately after Jackson Storm debuted at the 2016 Dinoco 400.
- His 1:55 diecast depicts him with an orange spoiler, although in the movie he is depicted with a black spoiler.
- In the Florida 500, before he was hit, he had a Ryan "Inside" Laney/Jim Reverick spoiler.
- Unlike the other racers, Tim never had any rookie stripes.
