the wheel must change direction and move quickly to follow imperfections in the road surface. Increasing this weight decreases the wheel's ability to follow the undulations. Increased mass also contributes to centripetal force, inhibiting the wheel's ability to change yaw (turn). It acts like a gyroscope.
