A non-pneumatic tire includes: an outer annular portion having an outer periphery including a tread provided thereon; an inner annular portion provided inside the outer annular portion; and a plurality of link parts that each connect the outer annular portion and the inner annular portion, and are provided along a tire circumferential direction. The tread includes a cap rubber disposed on an outermost side in a tire radial direction, a first base rubber disposed more inwards in the tire radial direction than the cap rubber, and a second base rubber disposed more inwards in the tire radial direction than the first base rubber. When a rubber hardness of the first base rubber is defined as Gb1 and a rubber hardness of the second base rubber is defined as Gb2, Gb1<Gb2 is satisfied.

A non-pneumatic wheel having a hub (12), an outer tread band (200) and a plurality of spokes (100) connecting the hub (12) with the outer tread band (200), each of the plurality of spokes (10) having first and second support elements joined by a first elastomeric joint body (130) connecting the first support element to the second support element.

One aspect of this invention involves a process for producing a non-pneumatic tire comprising a structure and a shear band, said process comprising providing a structure comprising a thermoplastic material having a surface intended to be brought into contact with a shear band; pretreating the surface of the structure to obtain a pretreated surface; providing an atmospheric pressure plasma generated from a gas mixture; depositing a plasma polymerized coating layer from the atmospheric pressure plasma on the pretreated surface to produce a structure with a coated surface comprising a plasma polymerized coating layer; providing a shear band with a layer of rubber material and contacting the coated surface of the structure with said layer of rubber material; and co-vulcanizing the coated surface of the structure with the layer of rubber material of the shear band.

The invention provides in a first aspect a non-pneumatic tire and wheel assembly comprising an outer annular ring having a ground contacting tread portion and a shear band, one or more spoke disks, wherein each spoke disk is connected to the shear band, wherein each spoke disk has at least two spokes, wherein each spoke has a first leg and a second leg, wherein a continuous strip of reinforcement is received in the first leg and the second leg.

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 system cures and manufactures a partially-cured tire assembly. The system includes an annular hub member slid into a corresponding annular, radially inner surface, a plurality of elongate spacer members for maintaining corresponding uniform cavity dimensions by fastening the spacer members to the hub member with flap members thereby enclosing a radially outermost surface of each of the spacer members, a first annular curing platen for axially securing the hub member and spacer members relative to each other, a second annular curing platen for axially securing the hub member and spacer members relative to each other; and a plurality of elongate inserts.

A tyre for electric skateboards includes a hub and a tyre casing. The hub is sleeved with the tyre casing. The tyre casing is fixedly connected to the hub. An annular cavity is formed in the tyre casing in a circumferential direction of the tyre casing. A deformable shock absorption and noise reduction ring is fixedly disposed in the annular cavity.

A non-pneumatic tire includes an annular inner ring, an annular outer ring, and a support structure positioned between the annular inner ring to the annular outer ring. The support structure includes a multilayer structure of a rubber skim layer and a cord embedded in the rubber skim layer. The rubber skim layer has resistance to ozone exposure without need for a protective layer overlying the rubber skim layer. The rubber skim layer exhibits adhesion to embedded metallic cords. Methods of making a non-pneumatic tire include forming a multilayer structure by applying a skin layer directly over one or more cords.

A non-pneumatic tire defining axial, radial, and circumferential directions. The tire includes an annular lattice structure extending radially between an inner circumferential edge and an outer circumferential edge. The lattice structure exhibits topological polarization, with the inner circumferential edge being stiffer than the outer circumferential edge. The topological polarization includes asymmetry in mechanical response to opposing forces applied to the inner and outer circumferential edges. The lattice structure which provides topological polarization endows the tire with localized softness along the outer radius, which enables extreme absorption of asperities, without transferring significant forces to the axle. In some embodiments, the lattice structure further exhibits topological protection, including the topological polarization characteristics being maintained upon experiencing wear at the outer circumferential edge. In some embodiments, the lattice structure is, or is akin to, a Kagome lattice arrangement.

A spoke (100) for a tire attaching an outer tread to a hub, the spoke (100) having first and second spoke elements (142, 144) possessing spoke element reinforcements, the spoke elements (142, 144) joined by a joint body (130) comprised of an elastomer connecting the first spoke element (142) to the second spoke element (144) and a reinforcement membrane (132) extending from the first spoke element (142) to the second spoke element (144) and having a first end (172) and a second end (170) and a middle portion (174), the first end (172) lying closer to the first spoke element reinforcements than the middle portion (174) and the second end (170) lying closer to the second spoke element reinforcements than the middle portion (174) of the spoke reinforcement membrane (132).
