"Spinning" is relative, but this is not just a drag strip thing. The wheel is always turning faster (or slower) than the road if you're putting force through it. In 2nd gear acceleration it's probably about 5%, at top speed it might be 1-2% (to combat the aero drag). The tire moving exactly with the road is an illusion at all times if you're pushing it.
