A support structure for a non-pneumatic tire and a tire incorporating such support structure. A support membrane extends continuously between a radially-inner end and a radially-outer end. Joints may be positioned at each end. An annular band may be connected with the radially-outer end. A wheel, hub, or other structure may be connected with the radially-inner end.

A method of making a non-pneumatic tire includes providing an inner ring of elastomeric material and an outer ring of elastomeric material, and arranging the inner ring and the outer ring such that the inner ring is substantially coaxial with the outer ring. The method further includes providing a plurality of sheets of reinforced elastomeric material and forming the plurality of sheets into a plurality of U-shaped sheets. The method also includes arranging the plurality of U-shaped sheets between the inner ring and the outer ring, and curing the inner ring, the outer ring, and the plurality of U-shaped sheets.

A tire includes an inner hoop, an outer hoop, and a plurality of spokes extending from the inner hoop to the outer hoop. Each of the spokes includes a y-shaped base, including a radially extending stem, a first concave branch, and a second concave branch. The spokes further include a convex member extending from the first concave branch to the second concave branch.

Various example embodiments of a non-pneumatic tire, and methods for making the same, are disclosed. In one embodiment, a non-pneumatic tire is provided, the non-pneumatic tire comprising: a tread; at least one support ring, wherein the at least one support ring and the tread are concentric; at least one base element oriented between the tread and the at least one support ring; and a hub.

A pre-strained non-pneumatic tire has an inner ring, an outer ring, and a plurality of polymeric connecting elements extending from the inner ring to the outer ring. The pre-strained non-pneumatic tire made by a process that includes forming an initial non-pneumatic tire and straining at least a portion of one of the plurality of polymeric connecting elements.

A wheel device includes: a wheel member; a tire disposed on the outside of the wheel member, the tire comprising an inner layer, an outer layer, and a plurality of hollow pipes disposed between the inner layer and the outer layer, wherein an inner circumferential surface of the inner layer comprises grooves; a plurality of support members each having a circular arc shape; and a plurality of spoke members respectively connecting the wheel member to the plurality of support members. The plurality of spoke members are configured to move the plurality of support members between a first position and a second position. In the first position, each of the support members are disposed in the grooves. In the second position, each of the support members are disposed closer to a central axis of the tire than when the support members are in the first position.

A wheel assembly may include an inner rim to be coupled to the hub of the vehicle, and an outer rim surrounding the hub. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension permitting relative movement between the inner rim and the outer rim. The wheel assembly may also include tread assemblies carried by the outer rim. Each tread assembly may include a tread member support coupled to the outer rim, and spaced-apart tread members carried by the tread member support and defining a tread pattern therebetween. Each tread member may include at least one rubber layer, and at least one reinforcing layer in stacked relation.

A universal temporary wheel is provided that has a universal aperture pattern that is adapted to mate with different configurations of lug bolt patterns to enable the wheel to be used with various wheel hub configurations having various lug bolt patterns. The universal temporary wheel can be installed while a damaged wheel is being repaired to allow an automobile or other vehicle to be moved. Because the universal temporary wheel has a universal aperture pattern, the wheel can be used with a variety of wheel hub configurations and lug bolt patterns, thereby eliminating the need to stock a variety of temporary wheels having various aperture patterns.

The present invention provides a simulated inflatable wheel including a rim, a filler tire mounted on the rim, and a tire casing covering the filler tire and having a rolling portion in rolling contact with the external environment and an abutting portion extending from two sides of the rolling portion. The abutting portion is located between the rim and the filler tire. The abutting portion abuts against the rim and the filler tire respectively. A recessed portion is formed on at least one position of an outer surface of the filler tire. The present invention utilizes the recessed portion of the filler tire to generate space between the filler tire and the rim (or the tire casing), for providing a buffer when the filler tire is deformed and improving elasticity of the filler tire. The present invention further provides a stroller including the simulated inflatable wheel.
