As the wheel starts accelerating, the distance from the center will increase due to lateral slipping. Initially, this slipping is small, and the wheel moves in an almost ideal circle. However, as the slip velocity increases as a result of an increasing centrifugal force, the wheel starts to slide.
The sliding of the wheel can be understood by studying the force of friction on the wheel as a function of slip velocity. Note that as the slip velocity reaches a certain point, the force of friction decreases, sliding begins, and the wheel’s distance to the center quickly increases. Then, once the distance is large enough and the centrifugal force has become lower than the force of friction, the slip velocity decreases, and the wheel once again moves in a circle.
