Abstract
A collapsible wheel rim structure adapted to support an inflated tire including a rim formed from pivotally mounted rim sections, and an internal plate support for the rim which fits into an internal track on the rim. The disc is formed from sections slidably mounted together which when fully extended enclose the area within the rim and support the rim. Supplementary rim support can be provided with collapsible cross-bars which fit into prongs on the internal surface of the rim so that the cross-bars extend across the internal diameter of the rim.
