An adjustable wheel assembly is provided and includes two pairs of oppositely disposed rim sections. The wheel assembly is normally biased in a circular configuration by a resilient tire disposed over the rim sections. A device for movably mounting the rim sections is employed to move the rims from their circular configuration to an oval configuration. When positioned in the oval configuration the wheel assembly applies maintaining and releasing device to prevent and permit movement of the rim sections between the circular and oval position.
