A structurally supported, non-pneumatic wheel is provided. The wheel includes a hub constructed from a polymeric material, which can more readily resist deformation during an impact event and provide improvements in noise generation and manufacturing cost. A plurality of tension-transmitting web elements connect the hub with a compliant, load supporting band.

A structurally supported tire includes a ground contacting annular tread portion, an annular shear band and at least one spoke disk connected to the shear band, wherein the spoke disk has at least one spoke, wherein the spoke extends between an outer ring and an inner ring in a first parabolic curve. The spoke disk may further includes a second spoke having a second parabolic curve different from the first curve, and overlapping with the first spoke.

A non-pneumatic tire comprises a radially inner ring for contacting a vehicle rim, a radially outer ring and a support structure including spokes extending from the radially outer ring to the radially inner ring. The spokes delimit openings in the support structure, which extend in a width direction of the non-pneumatic tire. The non-pneumatic tire has a reinforcement structure comprising loops of reinforcement cord, each loop extending around one of the openings. Each spoke has arranged therein radial reinforcement cord segments extending radially between the inner ring and the outer ring. The radial reinforcement cord segments are lined up parallel to one another along the width direction of the non-pneumatic tire.

A tire and wheel assembly includes a tire, a circular hub member for securing to a rotatable axle of a vehicle, the rim piece having a first annular ring flange for engaging the tire, a rim piece for engaging the hub member, a second annular ring flange for engaging the tire, and a plurality of cylindrical shafts for each axially engaging the first annular ring flange at one axial end of each of the shafts and the second annular ring flange at another opposite axial end of each of the shafts.

A non-pneumatic tire is described that has an outer ring structure with a tread extending circumferentially around the axis, the outer ring structure extending transversally from the first to the second lateral side and comprising a first and second support ring on the first and second lateral side, respectively; an inner ring structure comprising a first and second base ring on the first and second lateral side, respectively; and a connecting structure, effective to transfer load from the inner ring structure to the outer ring structure, including a first set of metal spokes extending from the first support ring to one of the first and second base rings, and a second set of metal spokes extending from the second support ring to the other of the first and second base rings.
