that support an outer rim on which the running tread is placed. Between the spokes and the
tire hub, there is a matrix of deformable plastic structures which flex under the load and
return to their original form afterwards. Unlike traditional airless tires which use non-flexible
materials in the wheel design, the tweel gets its equivalent of air suspension from the
polyurethane spokes, which are flexible and temporarily deformable. This speci ...more
