Patent ID: 8851131

Claim:
A skew-symmetric, non-pneumatic tire rotatable about an axis comprising: two copies of a single, molded, side wall portion for a non-pneumatic tire creating a skew-symmetric structure that is rimless; a generally cylindrical hub surrounding the axis of rotation and a generally cylindrical outer surface sharing the common axis of rotation; wherein the two copies are a pair of disk-like side wall members comprising non-buckling webs extending between and mating with the generally cylindrical hub and the generally cylindrical outer surface; said pair of side wall members have webs sharing a common configuration resulting in an assembly with a skew-symmetric structure with respect to the loading direction; wherein the assembly is configured such that the webbing of each side wall member has the same visual image as the other side wall when rotated about the axis of loading, i.e. “anti-symmetric” or “rotationally symmetric”; wherein the assembly is configured such that the webbing of each side wall member has an opposing configuration to that of the other side wall; and a tread-band circumscribing the cylindrical outer surfaces of the side walls.
