There is provided a non-pneumatic tire (1) including: an attachment body (11) that is attached to an axle; a ring-shaped body (13) that surrounds the attachment body (11) from an outside in a tire radial direction, a plurality of connection members (15) that are disposed between the attachment body (11) and the ring-shaped body (13) along a tire peripheral direction and connect the attachment body (11) and the ring-shaped body (13) to each other, and a cylindrical tread member (16) that is externally mounted on the ring-shaped body (13), in which the ring-shaped body (13) and the connection member (15) are integrally formed by a injection molding in which a molding material is injected from the connection member (15) side toward the ring-shaped body (13) side, in which the tread member (16) includes a base rubber portion (41) that is positioned at an inside in the tire radial direction and a cap rubber portion (42) that is positioned at an outside of the base rubber portion (41) in the tire radial direction, in which rigidity of the base rubber portion (41) is lower than rigidity of the cap rubber portion (42), and in which the base rubber portion (41) is disposed at least in a portion positioned between the connection members (15) adjacent to each other in the tire peripheral direction in the ring-shaped body (13).

A variable compliance non-pneumatic wheel which comprises a stationary tubular body (32) attached to the vehicle chassis. A tubular member is freely rotatable relative to the stationary tubular body and has a series of peripheral mounting rods (12, 13) on sides of the wheel. A plurality of interconnected and freely rotating caterpillar-like tiles (5), which are in contact with the ground during wheel operation, are coupled to the outer periphery of the wheel. A plurality of connecting spring members, (3, 4, 6, 7, 8, 9, 10, 11), each connecting a specific mounting rod on a side of the hub (1, 2) are configured to connect the tiles (5) to the hub. The tubular member is split in two parts (1, 2) which are each free to rotate relative to one another. Each part carries approximately half number of mounting rods and connecting springs on a respective side of the wheel.

Tire-type device having bearing elements (7) within annular space (5) between inner and outer coaxial structures of revolution, the latter contacting the ground in contact patch (A). The bearing elements are independent in pairs and buckle under compression in contact patch (A). The smallest characteristic dimension E of the section S of any bearing element (7) is at most equal to 0.02 times the mean radial height H of the inner annular space (5), the surface density D of the bearing elements (7) per unit area of the radially outer structure of revolution, expressed in 1/m.sup.2, is at least equal to Z/(A*ΣFr/n), where Z is the nominal radial load, expressed in N, A is the area of contact with the ground, expressed in m.sup.2, and ΣFr/n is the mean force at break under tension of the n bearing elements made to buckle under compression, expressed in N.

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 tire includes a plurality of rim members disposed at different positions on a same axis, a plurality of body springs that connect between the respective plurality of rim members, and an interlink member that interlinks the adjacent body springs. Each of the plurality of body springs includes an elastic deformable portion, and latch portions that are provided at both ends of the elastic deformable portion and have a different shape from the elastic deformable portion. The latch portions are latched on the rim members.

A wheel for a vehicle is non-pneumatic (i.e., airless), may be designed to enhance its use and performance and/or use and performance of the vehicle, and may be manufactured efficiently, including by a single non-pneumatic tire molding operation that can allow rigid rim incorporation and complex tread implementation.
