A non-pneumatic tire includes an inner ring having an axis of rotation and an outer ring coaxial with the inner ring. The non-pneumatic tire further includes support structure extending from the inner ring to the outer ring. The support structure is constructed of a thermoplastic material and having reinforcement cords embedded therein. The non-pneumatic tire also includes a circumferential tread extending about the outer ring.

A tire includes a plurality of SMA springs. Each SMA spring includes a first end portion, a second end portion, and an arching middle portion. Each SMA spring is interlaced with at least one other SMA spring thereby forming a laced toroidal structure extending about an entire circumference of the tire.

A wheel and tire assembly a plurality of includes support elements for supporting part of a load of a vehicle and an annular shear band extending circumferentially around the support elements. The shear band has a radially inner circumferential membrane, a radially outer circumferential membrane, and a shear layer interconnecting the inner membrane and the outer membrane for controlling shear deflection between the inner membrane and the outer membrane. The shear layer defines a connecting film layer radially sandwiched between a first radially inner, cylindrical flat film layer and a second radially outer, cylindrical film layer. The connecting film layer defines a periodic wave shape as the connecting film layer extends circumferentially between the first and second film layers.

A method of manufacturing an airless tire including a spoke unit includes a first step of injection-molding a first spoke part, a second spoke part, a third spoke part and a fourth spoke part in a disc-like shape. The method further includes a second step of forming a first spoke by fusing the first spoke part and the second spoke part. The method further includes a third step of forming a second spoke by fusing the third spoke part and the fourth spoke part, and a fourth step of forming the spoke unit by fusing the first spoke and the second spoke.

A non-pneumatic tire is provided. The non-pneumatic tire includes an outer annular portion, an inner annular portion, and a load bearing ring positioned between the outer annular portion and the inner annular portion. The load bearing ring includes at least one reinforcing layer, and each of the at least one reinforcing layers includes one or more strips of multi angle tension control reinforcement (MATCR) material.

A nonpneumatic tire assembly includes an outer hoop, a plurality of loops extending inward from the outer hoop, and a hub having a plurality of members. Each of the plurality of members is connected to one of the plurality of loops.

A structurally supported tire includes a ground contacting annular tread portion, an annular hoop structure for supporting a load on the tire, a means for attachment to a vehicle rim, and a ply structure secured to a first axial limit and extending radially outward and between the hoop structure and the tread portion and further extending radially inward from between the hoop structure and tread portion to a second axial limit. The ply structure is secured to both the first axial limit and the second axial limit. The tread portion is secured to a radially outer surface of the ply structure. The hoop structure is secured to a radially inner surface of the ply structure.

A non-pneumatic tire is provided. The non-pneumatic tire includes an outer annular portion, an inner annular portion, and a load bearing ring positioned between the outer annular portion and the inner annular portion, the load bearing ring including an inner layer of matrix material, an outer layer of matrix material, and a wave shaped spring positioned between the inner layer of matrix material and the outer layer of matrix material.
