A non-pneumatic tire includes a rim part configured to be coupled to an axle; a tread part formed in a shape of surrounding an outer side of the tire in a circumferential direction thereof and being in contact with the ground; a spoke part which is formed between the rim part and the tread part and is provided with an upper arch bodies and lower arch bodies of an arch shape to absorb impacts transmitted from the ground to the tread part; and a structural reinforcement part which is inserted into the inside of the tread part and is provided with a cord sheet member comprising a plurality of wires to perform load support and stress distribution of the spoke part.

A shear band comprising a three-dimensional spacer structure, wherein the three-dimensional spacer structure is formed from a first and second layer of material, each layer of material having first reinforcement members which extend in a first and direction, and second reinforcement members which extend in a second direction, wherein each layer of material is connected to each other by a plurality of connecting reinforcement members which extend in a third direction, wherein the shear band further comprises a first membrane layer located radially outward of the three-dimensional spacer structure. The invention further comprises a non-pneumatic tire which includes the above described shear band.

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.

The invention relates to a vehicle wheel assembly, comprising 1) a wheel rim having two opposed circular rim flanges; 2) an outer tire having two beads secured at the circular rim flanges; 3) an inlay; 4) a non-pneumatic inner tire comprising expanded thermoplastic polyurethane (E-TPU), which inner tire is enclosed by the outer tire, the inlay and the wheel rim. The inner tire in the assembly is in a compressed state S1, which state is compressed as compared to a relaxed state S2 when the inner tire is not enclosed by the outer tire, the compression being such that the cross-sectional surface area SA of the inner tire, which area is perpendicular to the plane of the tire, is smaller in state S than in state S2.

A method for producing a tire filled with a (meth)acrylic hydrogel, the method comprises a) providing a mixture comprising at least one water-soluble (meth)acrylic compound, water and an initiator, and b) filling the mixture in a tire in which the mixture polymerizes to form the (meth)acrylic hydrogel. The tire filling material is suitable for producing flat proof tires, enables fast and controlled cure and is insensitive towards dosage errors. Moreover, the tire filling material is environmental friendly and cost effective.

A tire for a vehicle has a structure in which a plurality of air blocks are detachably mounted in a circumferential direction of the tire. The tire is similar to an airless tire, in which a plurality of spokes are connected to and arranged between a tread rim part configured to come into contact with a road surface and a hub which is mounted to the wheel, and the tire is also similar to a pneumatic tire, in which an air block is replaceably inserted and mounted into an air block mounting space formed between the spokes.

A non-pneumatic tire includes a rim part configured to be coupled to an axle; a tread part formed in a shape of surrounding an outer side of the tire in a circumferential direction thereof and being in contact with the ground; a spoke part which is formed between the rim part and the tread part and is provided with an upper arch bodies and lower arch bodies of an arch shape to absorb impacts transmitted from the ground to the tread part; and a structural reinforcement part which is inserted into the inside of the tread part and is provided with a cord sheet member comprising a plurality of wires to perform load support and stress distribution of the spoke part.

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 shear band comprising a three-dimensional spacer structure, wherein the three-dimensional spacer structure is formed from a first and second layer of material, each layer of material having first reinforcement members which extend in a first and direction, and second reinforcement members which extend in a second direction, wherein each layer of material is connected to each other by a plurality of connecting reinforcement members which extend in a third direction, wherein the shear band further comprises a first membrane layer located radially outward of the three-dimensional spacer structure. The invention further comprises a non-pneumatic tire which includes the above described shear band.

An airless tire includes a tread ring having a cylindrical form and a ground contact surface. The tread ring has multiple through holes and a reinforcing body such that the through holes are penetrating through the tread ring in a thickness direction of the tread ring and formed at intervals along a tire circumferential direction and that the reinforcing body includes a first reinforcing body extending in the tire circumferential direction in regions between adjacent through holes, and the first reinforcing body is formed such that the first reinforcing body has end portions in the tire circumferential direction and that the end portions terminate without being exposed from inner peripheral surfaces of the through holes.
