A shear band and a non-pneumatic tire is described which includes a ground contacting annular tread portion; a shear band, and a connecting web positioned between a hub and the shear band. The shear band is preferably comprised of a three-dimensional spacer fabric having a first and second layer connected by connecting members. The three-dimensional spacer fabric has a defined depth. The three-dimensional spacer structure further includes a plurality of cells formed between the connecting members, and wherein one or more of the cells are filled with a filler material. The filler material may be foam or a thermoplastic elastomer.

A non-pneumatic tire is described that includes a ground contacting annular tread portion, a shear band, wherein the shear band is formed of a first and second inextensible layer, and a low modulus material positioned between the first and second inextensible layer. The non-pneumatic tire further includes a connecting web positioned between a hub and the shear band, wherein the connecting web is formed of one or more spokes extending from an inner ring to an outer ring, wherein the one or more spokes are formed from a material reinforced with a three dimensional spacer structure.

A shear band comprising a three-dimensional spacer structure, wherein the three-dimensional spacer structure is formed from a first and second layer of material, each layer of material having first reinforcement members which extend in a first and direction, and second reinforcement members which extend in a second direction, wherein each layer of material is connected to each other by a plurality of connecting reinforcement members which extend in a third direction, wherein the shear band further comprises a first membrane layer located radially outward of the three-dimensional spacer structure. The invention further comprises a non-pneumatic tire which includes the above described shear band.

An airless tire has a tread ring provided with a reinforcing rubber layer disposed radially inside a tread rubber layer and made of a rubber compound [A] comprising: 100 parts by mass of the rubber component containing 10 to 100% by mass of butadiene rubber; 10 to 80 parts by mass of an metal salt of an alpha beta unsaturated carboxylic acid; and a peroxide. A barrier layer, which restrains sulfur in an adjacent rubber compound from migrating into the reinforcing rubber layer, is disposed between the reinforcing rubber layer and the adjacent rubber compound.

A non-pneumatic tire includes an inner ring, an outer ring, and a plurality of bent metal spokes. The non-pneumatic tire further includes a first overmolded foot at a first end of each bent metal spoke. Each first overmolded foot is attached to the inner ring. The non-pneumatic tire also includes a second overmolded foot at a second end of each bent metal spoke. Each first overmolded foot is attached to the outer ring.

A non-pneumatic tire (1) includes three or more tubular bodies (2) and a plurality of elastically deformable connecting members (3) interconnecting the tubular bodies (2) and disposed along a tire circumferential direction in each annular space (9) provided between the tubular bodies (2) adjacent to each other in a tire radial direction. The tubular bodies (2) are provided with an inner tube (6) positioned on an innermost side in the tire radial direction and attached to an axle, an outer tube (4) positioned on an outermost side in the tire radial direction, and an elastically deformable intermediate tube (8) positioned between the inner tube (6) and the outer tube (4). The connecting member (3) is provided with a pair of connecting plates (21 and 22) having both end portions in the tire radial direction directly connected to the tubular body (2) and extending in the tire radial direction and separated in the tire circumferential direction from an outside toward an inside in the tire radial direction. A position (P1) of connection to the pair of connecting plates (21 and 22) connected to the intermediate tube (8) from the outside in the tire radial direction and a position (P2) of connection to the pair of connecting plates (21 and 22) connected to the intermediate tube (8) from the inside in the tire radial direction are shifted in the tire circumferential direction in the intermediate tube (8).

A method of mounting a non-pneumatic tire onto a hub to provide a non-pneumatic wheel is provided. Certain portions of spokes of the non-pneumatic tire are connected to grooves along the hub. The tire is repeatedly rotated and deformed to allow the remaining portions of the spokes to be connected with the grooves in order to fully mount the tire onto the hub.
