Tractor Rob is mostly right, and you have seen this effect before in just about all car video. If the object is moving slower than the frame rate, the rotation will look normal. If the frame rate is equal, the object/moving tires, will appear to stand still. If the object is going faster than the frame rate of the video, the object/tires will appear to be moving in reverse.
In the Navy, tuning electronics equipment, we used something similar called the strobe effect to tune motors in navigation gear to a certain speed, and the effect was the same.
