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 non-pneumatic tire includes a generally annular inner ring that attaches to a wheel, a generally annular outer ring, and an interconnected web between the generally annular inner ring and the generally annular outer ring. The interconnected web defines a plurality of openings circumferentially spaced around the tire and radially spaced at varying distances from an axis of rotation, so as to support a load by working in tension. The interconnected web includes a plurality of web elements having a varying thickness, including a first plurality of web elements above the axis of rotation and a second plurality of web elements below the axis of rotation. The varying thickness is configured to facilitate buckling of the interconnected web. When a load is applied, the first plurality of web elements are subjected to a tensile force while the second plurality of web elements buckle.

A non-pneumatic tire is described that includes a ground contacting annular tread portion, a shear band, wherein the shear band is formed of a first and second inextensible layer, and a low modulus material positioned between the first and second inextensible layer. The non-pneumatic tire further includes a connecting web positioned between a hub and the shear band, wherein the connecting web is formed of one or more spokes extending from an inner ring to an outer ring, wherein the one or more spokes are formed from a material reinforced with a three dimensional spacer structure.

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 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 may comprise a hub and a plurality of discrete traction elements coupled to the hub. Each of the traction elements may comprise a backing plate and an elastomeric material bonded to the backing plate. Circumferentially adjacent traction elements may axially overlap.

An adhered composite includes (i) a polar thermoset substrate; (ii) optionally a primer layer disposed on the polar thermoset substrate; (iii) a first adhesive layer adhesively mated to the polar thermoset substrate, optionally with the primer layer disposed between the first adhesive layer and the polar thermoset substrate; (iv) a first layer of cured non-polar rubber adhesively mated to the first adhesive layer; (v) a second adhesive layer adhesively mated to the first layer of cured non-polar rubber; and (vi) a second layer of cured non-polar rubber forming an outer surface of the composite.

A system manufactures a tire assembly. The system includes a core having a cylindrical hub and radially protruding extensions projecting radially outward from the hub, a plurality of internal arcuate members for positioning a reinforcing layer of the about the core, the internal arcuate members each being wrapped with a reinforcement layer, the internal arcuate members being disposed in spaces circumferentially between the extensions of the core, a first side plate for securing the internal arcuate members in place relative to the core; and a second side plate for securing the core and internal arcuate members to each other.

A wheel assembly may include an inner rim to be coupled to the hub of the vehicle, and an outer rim surrounding the inner rim. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim and permitting relative movement therebetween. The wheel assembly may also include a rigid inboard cover ring coupled to an inboard side of the outer rim and extending radially inward toward the inner rim. A flexible inboard seal may be coupled between the rigid inboard cover ring and the inner rim.

A wheel assembly to be coupled to a hub of a vehicle may include an inner rim to be coupled to the hub of the vehicle and an outer rim surrounding the hub. The wheel assembly may also include gas springs operatively coupled between the inner rim and the outer rim to provide a gas suspension for relative movement between the inner rim and the outer rim. The wheel assembly may also include a disk coupled to the inner rim. The wheel assembly may also include inboard lateral stops carried by an inboard interior surface of the outer rim, and outboard lateral stops carried by an outboard interior surface of the outer rim so that the inboard lateral stops and the outboard lateral stops cooperate to limit relative lateral movement of the disk and the outer rim.
