I agree with the answers so far.
It does look like your wheel rotation is a little too fast, how many frames are you using for one loop of the track?
There was a guy some years ago, Einstein was his name, Albert Einstein, he once wrote about time dilation – the theory of relativity.
In this case, when you view the animation from the perspective of the camera, which is travelling at the same speed as the car, albeit rotating around the car, the variations in speed are less or unnoticeable, compared to a static view of the car racing around the track.
You can see the speed variation from the camera view if you focus on the background and not the truck.
