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.

The disclosed technology generally relates to a tire, and more particularly to a non-pneumatic tire that has handling performance similar to a pneumatic tire, supports the load of a vehicle and improves riding comfort by employing a parametric structure. In one aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that functions as a structural support between the rim and the tread, in which the spoke unit is formed by circularly arranging spokes. The spokes have a single closed-loop longitudinal cross-section circumscribed to the rim and around the center of the tire.

A structurally supported tire includes a ground contacting annular tread portion, an annular hoop structure for supporting a load on the tire, and a ply structure secured to a vehicle rim and the tread portion. The hoop structure is secured to a radially inner surface of the ply structure. The hoop structure includes a first double layer of steel cords and a second double layer of steels cords sandwiching a first layer of non-woven reinforcement, a second layer of non-woven reinforcement, and a single layer of steel cords.

An adjustable airless tire system includes supporting rods connecting with walls of a tire and a metallic hawser loop, which transfer a load of a vehicle from a ground contact surface of the tire to whole walls of the tire. A sensor detects a tension of the tire and a variation of the tension during driving. A control component adjusts the tension of the tire according the load of the vehicle and the road conditions to improve its oil saving, comfortability, controllability and safety. A rim of a wheel keeps an appropriate distance from the tire to limit the maximal level of downward movement of the supporting rods, and support the load of the vehicle if the tire is overload or the supporting rods lose their function. A curved tire forms closed space between the tire and the rim of the wheel to prevent sticking of foreign objects between them.

A non-pneumatic tire includes a lower ring having a first diameter and an upper ring having a second diameter greater than the first diameter. The upper ring is substantially coaxial with the lower ring. Support structure connects the lower ring to the upper ring. At least one of the lower ring, the upper ring, and the support structure includes a fiber metal laminate having at least one metal foil layer and at least one fiber and resin combination layer.

A tire includes an inner hoop, an outer hoop, and a plurality of spokes extending from the inner hoop to the outer hoop. Each of the spokes includes a y-shaped base, including a radially extending stem, a first concave branch, and a second concave branch. The spokes further include a convex member extending from the first concave branch to the second concave branch.

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.
