WHEEL AND TIRE ASSEMBLY

摘要

A wheel assembly is disclosed, the wheel assembly including a rigid wheel including a radially outer rim wall presenting a polygonal shape with a plurality of outermost vertices connecting a plurality of planar faces, and a flexible tire mounted on the outer rim wall. The tire is supported by the vertices of the rim wall and is separated from the rim faces by a space, portions of the tire located between the vertices being configured to flex inwardly when subject to ground engaging pressure.
