The present invention provides an annular beam of monolithic construction of one homogeneous material and a related efficient, low-cost non-pneumatic tire. Specific geometric design, combined with nonlinear elastomer physical properties, enable the suppression of all reinforcing belts, continuous fibers, or other strengthening layers in the annular beam. The annular beam consists of at least two bands that are continuous in the circumferential direction and connected by a web geometry. The non-pneumatic tire consists of the annular beam, a ground contacting portion, a central wheel, and a plurality of web spokes that connect the wheel and beam. When the tire is loaded to a design load against a flat surface over a design contact length, a contact area of essentially uniform pressure is produced, while the load is transmitted from the beam to the hub via tension in the web spokes. The tire can be economically manufactured.

The provided tire has excellent durability regardless of use in a high-humidity environment or contact with water, even though the framework member of the tire is made of a resin material. The resin material is made of a resin composition including 60 mass % or more of a polyamide resin formed by polymerizing an aliphatic diamine having 6 to 20 carbon atoms and an aliphatic dicarboxylic acid having 10 to 20 carbon atoms.

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 tire assembly about the core, the internal arcuate members being disposed in spaces 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 non-pneumatic tire and hub assembly includes an inner ring having an axis of rotation, a deformable outer ring, and a flexible web extending between the inner ring and the deformable outer ring. The assembly further includes a hollow, metal cylinder coupled to the inner ring. The hollow, metal cylinder has a flanged portion extending towards an interior portion of the hollow, metal cylinder.

A shear band that may be used e.g., in a non-pneumatic tire is provided. The shear band uses interlaced reinforcing elements positioned within a shear layer of elastomeric material. A variety of configurations may be used to create the interlaced positioning of the reinforcing elements including e.g., a horizontal diamond or vertical diamond configuration. The shear layer formed from a rubber composition having a very low hysteresis.

A non-pneumatic wheel (100) including a hub (300) and a non-pneumatic tire (102), as well as a method for mounting the non-pneumatic tire (102) onto the hub (300). The hub (300) is formed, with grooves (318) that receive the radially-inner ends (110) of spokes (106) of the non-pneumatic tire (102). To secure the tire (102) onto the hub (300) during assembly, the grooves (318) with the radially inner ends (110) of the spokes (106) received therein are pulled radially inward to decrease the diameter of the hub (300) and increase tension in the spokes (106).
