Foam tires then tend to pick up those carpet fibers and lose traction once the foam tires get coated with carpet fuzz. Since the WGTs have such big tires, they are way less sensitive to the fuzz issue than are the 1/12th scale cars. The big WGTs foams also do a really good job of laying down traction for the cars that follow.
