In accordance with one implementation of the present principles, the toy model tires are designed to be divided into sections. Each divided tire section independently pivots on its own fixed fulcrum point. In response to terrain conditions, the tires can transform by the pivoting of the tire sections outward, thus increasing the outer diameter and causing the tire to take on a claw like form to assist in overcoming rough terrain or obstacles on a running surface.
