A tire comprising a continuous channel defined by spaced apart sidewalls coupled at a first end to a bridging member and at a second end to a contact member that is coupled to a disc contact portion, said tire being formed by rotational molding of a polyurethane and configured for mounting on a wheel rim.

A molded body is useful in non-pneumatic tires. The non-pneumatic tires containing the molded body are useful for vehicle wheels such as wheels for cars, bikes, motorcycles, trucks, e-scooters, toys, sports equipment, golf caddy, strollers, or wheelchairs. A process for manufacturing the molded body for non-pneumatic tires is also provided.

A wheel and tire assembly a plurality of includes support elements for supporting part of a load of a vehicle and an annular shear band extending circumferentially around the support elements. The shear band has a radially inner circumferential membrane, a radially outer circumferential membrane, and a shear layer interconnecting the inner membrane and the outer membrane for controlling shear deflection between the inner membrane and the outer membrane. The shear layer defines a connecting film layer radially sandwiched between a first radially inner, cylindrical flat film layer and a second radially outer, cylindrical film layer. The connecting film layer defines a periodic wave shape as the connecting film layer extends circumferentially between the first and second film layers.

A non-pneumatic tire of the present invention includes an inner tube (6) attachable to an axle (15a), an outer tube (4) configured to surround the inner tube from an outer side in a tire radial direction, an elastically deformable connecting member (3) configured to connect the inner tube and the outer tube to each other, and a tread member (5) fitted onto the outer tube. A space is formed in a portion of the tread member in which a wheel tread of the tread member is avoided.

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 tire, a wheel, and a vehicle are provided. The tire includes a tire body. The tire body has a plurality of cavities along the circumferential direction, each of the plurality of cavities has an opening located on an inner circumferential surface of the tire body, a connecting portion is formed between adjacent openings, the connecting portion comprises a middle connecting portion and an end connecting portion distributed along a width direction of the tire body, and a width of the middle connecting portion is constant.

A module, usable with a plurality of other modules, to obtain an annular modular assembly adapted to fill a tire of a cycle or motorcycle. The module can be removably inserted into the tire and includes a body made of foamed elastomeric material defining a portion of the annular modular assembly. The body has a shape of circular or ellipsoidal section with tapered end areas designed, in use, to remain facing or in contact with one of the tapered end areas of the adjacent modules. The tapered end areas define respective planes converging toward the center of the tire and angularly spaced by an angle between 8? and 30?.

The present application relates to a tire (2) comprising a tread portion (4) and sidewalls (6) terminating with beads, with inner sides defining an annular cavity; a deformable structure (8) located in the annular cavity in contact with the inner side of the tread portion (4), said structure (8) comprising bendable elements (10); wherein the bendable elements (10) of the deformable structure (8) comprise a piezoelectric material (10.sup.2) so as to produce electrical energy from bending of said elements (10) and comprise at least one thermoelectric material (10.sup.1, 10.sup.3) so as to produce electrical energy from heat of said elements.

A disclosed example embodiment of a gauge wheel tire includes a first polyurethane sidewall portion, a second polyurethane sidewall portion, a polyurethane ground-engaging portion, and a polyurethane axial support portion. The first polyurethane sidewall portion is spaced apart from the second polyurethane sidewall portion, and the polyurethane ground-engaging portion extends from the first polyurethane sidewall portion to the second polyurethane sidewall portion and is adapted to contact a ground surface as the gauge wheel tire rotates about an axis of rotation. The polyurethane axial support portion extends from the first polyurethane sidewall portion to the second polyurethane sidewall portion, and is spaced apart from the polyurethane ground-engaging portion to form a gap that allows radial movement of the polyurethane ground-engaging portion relative to the polyurethane axial support portion.

A tire comprising a continuous channel defined by spaced apart sidewalls coupled at a first end to a bridging member and at a second end to a contact member that is coupled to a disc contact portion, said tire being formed by rotational molding of a polyurethane and configured for mounting on a wheel rim.
