The web structure further includes a second corrugated ring having a second plurality of peaks and a second plurality of valleys. The second corrugated ring is a metal ring. The second plurality of valleys are affixed to the first plurality of peaks by brazing or welding.

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 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 central region configured to be mounted to a wheel and a crown region including a circumferential tread and a shear element disposed below the circumferential tread. The shear element includes an upper reinforcement layer, a lower reinforcement layer, and an elastic region disposed between the upper reinforcement layer and the lower reinforcement layer. A radial distance between the upper reinforcement layer and the lower reinforcement layer varies along an axial width of the tire. The tire also includes an intermediate region extending from the central region to the crown region.

A non-pneumatic tire includes an inner ring having an axis of rotation and an outer ring having a plurality of circumferential reinforcements. The non-pneumatic tire further includes support structure extending from the inner ring to the outer ring. The non-pneumatic tire also includes a circumferential tread extending about the outer ring. The circumferential tread includes a tread reinforcement layer spaced from a bottom of the circumferential tread.

A non-pneumatic tire including an inner cylinder, an outer cylinder, and a connecting member. The outer cylinder and the connecting member elastically deformable. A thickness of a thickest part of the outer cylinder is thicker than a thickest part of the connecting member. The connecting member includes a vertical base portion that extends toward the inside in the tire radial direction from the outer cylinder's inner peripheral surface. A horizontal base portion extends along the tire circumferential direction from an inner end portion in the tire radial direction of the vertical base portion toward one side in the tire circumferential direction. An inclined portion gradually extends toward one side in the tire circumferential direction from an end portion on one side in the tire circumferential direction of the horizontal base portion toward the inside in the tire radial direction and is connected to the inner cylinder's outer peripheral surface.

A non-pneumatic or pneumatic tire includes an area for tire indicia or markings. The tire includes a hub region and a tread layer. The tread layer of the tire has a shoulder with a cut out extending either partially or entirely around the shoulder of the tire tread layer. The angle of the notched or beveled portion is 45-135° with respect to an axial direction along the tread layer shoulder, and at least one indicia disposed on the at least one flat surface. The placement of the markings may be radially along the surface of the cut out portion or axially along the surface of the cut out portion. The markings may be recessed, stamped, molded, painted or applied with ink to the cut out portion. Alternatively, the indicia or marking may be applied to a decal and applied to the cut out portion.
