  1. As the wheel turns it uses a different diameter rotation as it rolls around the tire. This speeds up the rotation, as it is carrying the energy over the shorter distance of the inside edge of the tire. ...so the faster rotation, pulls the bike, which in turn pulls if the turned wheel and straightens it up. TL/DR The tire rotation diameter did it
