With almost 5 minutes remaining in the movie, Vin is going to race to the railroad tracks that are only 1/4 mile away. As he leaves the start position you can clearly see that he has hard-walled tires on his car. When it shows the picture of his spinning out and the car's front end leaving the ground you can see that the car has soft-walled tires on it. This may defy the physics, but perhaps it shouldn't be noticeable as it is.
