A wheel assembly for a tire includes a circular hub member for securing to a rotatable axle of a vehicle, a first rim piece for engaging the hub member, a second rim piece for engaging the first rim piece, and a plurality of cylindrical sleeves for engaging both the first rim piece and the second rim piece. The first rim piece has cylindrical first shafts each engaging a first end of one of the sleeves. The second rim piece has cylindrical second shafts each engaging a second opposite end of one of the sleeves. An outer cylindrical surface of each sleeve engages a separate and distinct part the tire.

A non-pneumatic wheel includes an outer band, a hub and a plurality of spokes formed from a polyamine material. Each of the plurality of spokes is displaced to create pretension in the radial direction under a design load and the displacement is equal to or greater than the predetermined deflection of the outer band. The plurality of spokes is made from a polyamide material having a conditioned tensile modulus between 600 MPa and 3000 MPa, an equilibrium moisture content of no more than 1.5%, and a fatigue failure resistance that can withstand at least 1 million cycles.

A structurally supported, non-pneumatic wheel is provided. The wheel includes a hub constructed from a polymeric material, which can more readily resist deformation during an impact event and provide improvements in noise generation and manufacturing cost. A plurality of tension-transmitting web elements connect the hub with a compliant, load supporting band.

A tire is configured to be received by a wheel having at least one angled surface. The tire includes a tread portion, a first sidewall, and a second sidewall. The first sidewall has a first outer surface, a first inner surface, and a first projection extending inwardly from the first inner surface. The first projection has a first angled surface configured to engage a first corresponding surface of a wheel. The second sidewall has a second outer surface, a second inner surface, and a second projection extending inwardly from the second inner surface. The second projection has a second angled surface configured to engage a second corresponding surface of the wheel.

An agricultural implement comprises a wheel body with a peripheral groove, a tire with a bead projecting radially inward, and a radial lock which locks the tire around the wheel body. The bead is shaped so as to be housed in the groove when the tire is mounted around the wheel body. The radial lock comprises a first aperture formed in the wheel body, opening into the groove on the one hand and onto a main face of the wheel body on the other hand, at least a second aperture formed in the bead of the tire, opening substantially facing the first aperture, and a pin placed in the first aperture and the second aperture.
