A non-pneumatic tire and hub assembly includes an inner ring having an axis of rotation, a deformable outer ring, and a flexible web extending between the inner ring and the deformable outer ring. The assembly further includes a hollow, metal cylinder coupled to the inner ring. The hollow, metal cylinder has a flanged portion extending towards an interior portion of the hollow, metal cylinder.

A non-pneumatic tire includes a support structure for supporting a load from a vehicle. The support structure includes an inner annular portion, an outer annular portion concentrically provided on an outer side of the inner annular portion, and a plurality of connecting portions which connect the inner annular portion and the outer annular portion to each other and are provided in a tire circumferential direction independently of one another, the plurality of connecting portions are configured such that elongated plate-like first connecting portions and elongated plate-like second connecting portions are arrayed along the tire circumferential direction, a plate thickness is smaller than a plate width, a plate thickness direction is oriented to the tire circumferential direction, and a plate thickness at a tire radial direction inner end coupled to the inner annular portion is larger than a plate thickness at a tire radial direction center portion.

A wheel and tire assembly includes a plurality of support elements for supporting part of a load of a vehicle and an annular shear band extending circumferentially around the support elements. The band has a radially inner circumferential membrane, a radially outer circumferential membrane, and a shear layer interconnecting the inner membrane and the outer membrane. The shear layer has a plurality of closed cells for controlling shear deflection between the inner membrane and the outer membrane.

A system manufactures a tire assembly. The system includes a core having a cylindrical hub and radially protruding extensions projecting radially outward from the hub, a plurality of internal arcuate members for positioning a reinforcing layer of the about the core, the internal arcuate members each being wrapped with a reinforcement layer, the internal arcuate members being disposed in spaces circumferentially between the extensions of the core, a first side plate for securing the internal arcuate members in place relative to the core; and a second side plate for securing the core and internal arcuate members to each other.

A tire for a mobile vehicle includes an outer flexible ring mounted to an inner central rim and a spoke structure extending radially between the inner central rim and the outer flexible ring. The spoke structure is constructed from a plurality of elements disposed side-by-side such that the elements extend circumferentially around the perimeter of the inner central rim and radially inside the outer flexible ring. The spoke structure further defines a plurality of triangular openings disposed between the outer flexible ring, a first element of the plurality of elements and a second element of the plurality of elements. The first element is circumferentially adjacent the second element.

A support structure for a non-pneumatic tire and a tire incorporating such support structure. A continuous membrane extends between a radially-inner leg and a radially-outer leg. Joints and reinforcement may be provided on sides of the membrane. An annular band may be connected with the radially-outer leg. A wheel, hub, or other structure may be connected with the radially-inner leg.

A non-pneumatic tire includes a rim part configured to be coupled to an axle; a tread part formed in a shape of surrounding an outer side of the tire in a circumferential direction thereof and being in contact with the ground; a spoke part which is formed between the rim part and the tread part and is provided with an upper arch bodies and lower arch bodies of an arch shape to absorb impacts transmitted from the ground to the tread part; and a structural reinforcement part which is inserted into the inside of the tread part and is provided with a cord sheet member comprising a plurality of wires to perform load support and stress distribution of the spoke part.

A non-pneumatic tire comprises: a band part including an inner band and an outer band, the outer band being separated from the inner band by a predetermined distance to surround the inner band; and a spoke part provided to extend in a circumferential direction of the tire between the inner band and the outer band, the spoke part including one or more holes when viewed in the circumferential direction and one or more holes when viewed in an axial direction of the tire.

A tire for sand traction includes a ground-engaging tread that is disposed radially outwardly of a wheel. Structural elements extend radially between the wheel and the tread. The tread includes an inboard shoulder and an outboard shoulder. The tread is formed with a recess wall that extends laterally between the inboard shoulder and the outboard shoulder. The recess wall is disposed radially inwardly of the inboard shoulder and the outboard shoulder to form a central recess. The tire also includes a plurality of circumferentially-spaced, laterally-extending lugs. Each lug extends across the central recess from the inboard shoulder to the outboard shoulder.

An improved wheel for a mobility apparatus designed is disclosed herein. The wheel conforms to obstacles in the ground, creating a smoother walking experience. The inner web of a tire of the wheel preferably consists of polygonal reliefs offset from each other over multiple layers in a radially symmetric pattern to create a web which naturally compresses to absorb shock from obstacles. The tire's inner core preferably consists of a hexagonal membrane that extends parallel to the axel of the tire and extends out of each side of the wheel such that it is visible.
