A tire and wheel assembly includes a non-pneumatic tire and a wheel. The non-pneumatic tire incudes a tread, an inner liner, and a plurality of spokes extending between and coupling the tread to the inner liner. The plurality of spokes have a first width and the inner liner has a second width greater than the first width such that a pair of inner liner flanges extend beyond the plurality of spokes in an axial direction. The wheel includes a rim and the inner liner is configured to be mounted on the rim with the pair of inner liner flanges fastened to the rim such that the non-pneumatic tire is serviceably mounted on the wheel.

An object of the present disclosure is to provide a non-pneumatic tire having a small temperature dependence of ride comfort, providing a good ride comfort over a wide temperature range, and having an excellent durability. A solution thereto is a non-pneumatic tire (1) using a resin composition for a framework member, the resin composition having a bending modulus of elasticity at −20° C. according to ISO 178 of 1600 MPa or less, and a bending modulus of elasticity at 60° C. according to ISO 178 of 150 MPa or more.

A wheel assembly for a non-pneumatic tire includes a wheel including an inboard side, an outboard side, and an outer surface, the outer surface including at least one taper extending from the inboard side to the outboard side, and a locking ring configured to abut against at least one of the inboard side and the outboard side of the wheel and to secure the non-pneumatic tire to the wheel.

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 and a circumferential tread extending about the outer ring. The circumferential tread includes a band layer constructed of a single material and a tread rubber layer directly attached to the band layer.

A molding tool for forming a non-pneumatic tire includes a wheel portion cavity, a tread ring portion cavity, and a plurality of spoke cavities extending between the wheel portion cavity and the tread ring portion cavity. At least a subset spoke cavities within the plurality of spoke cavities include at least one of a non-uniform thickness, a non-uniform width, and a non-uniform surface. Also, the molding tool can include a conformal thermal control channel, e.g., a conformal cooling channel and/or a conformal heating channel, proximate to at least one mold cavity.

A wheel assembly for a non-pneumatic tire includes a wheel including an inboard side, an outboard side, and an outer surface, the outer surface including at least one taper extending from the inboard side to the outboard side, and a locking ring configured to abut against at least one of the inboard side and the outboard side of the wheel and to secure the non-pneumatic tire to the wheel.

An airless tire includes an inner wheel including flanges having fin fastening holes, an outer wheel receiving the inner wheel and including a tread part molded into the outer surface of a drum with at least one of through holes and irregularities to be united with the drum, with the inner periphery of the tread part embedded in the through holes or irregularities, a middle wheel including elastomers, a peripheral part having fin fastening holes and formed on the inner periphery of the elastomers, and ribs in the middle of the elastomers, a fixing device attaching the inside of the outer wheel to the outside of the middle wheel and then detachably uniting the middle wheel and the outer wheel, and coupling fins that allow the inner wheel and the middle wheel to be detachably held together by being inserted through the fin fastening holes and the fin fastening holes.

A tire comprising a plurality of cavities formed on each of the first and second tire sidewalls. The cavities are extending longitudinally from a cavity opening up to a predetermined distance in the radial middle portion, wherein each cavity comprises a bottom surface and at least one cavity sidewall surface extending from the bottom surface to the cavity opening, said bottom surface and at least one sidewall surface defining an unpressurised cavity space. At least one of the tire cavities comprises at least one structural element extending outwardly from at least one of the cavity surfaces.

A tire for a mobile vehicle includes an outer flexible ring mounted to an inner central rim and a spoke structure extending radially between the inner central rim and the outer flexible ring. The spoke structure is constructed from a plurality of elements disposed side-by-side such that the elements extend circumferentially around the perimeter of the inner central rim and radially inside the outer flexible ring. The spoke structure further defines a plurality of triangular openings disposed between the outer flexible ring, a first element of the plurality of elements and a second element of the plurality of elements. The first element is circumferentially adjacent the second element.

A web structure for a non-pneumatic tire includes a first corrugated ring having a first plurality of peaks and a first plurality of valleys. The first corrugated ring is a pre-strained, thermoplastic elastomer resin ring. 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 pre-strained, thermoplastic elastomer resin ring. The second plurality of valleys are affixed to the first plurality of peaks by welding or an adhesive.
