  • Publication number: 20210276367
    Abstract: A method of making a tire includes forming a first sheet of material having a circular shape. The first sheet of material includes an upper ring and a lower ring. The first sheet of material further includes a plurality of spoke portions extending from the upper ring to the lower ring. A reinforcement is placed on the first of polymeric material, which includes placing the reinforcement on at least a portion of the upper ring. A second sheet of material having a circular shape is formed. The second sheet of material is placed on the first sheet of material such that the reinforcement is sandwiched between the first and second sheets of material. The method further includes placing additional sheets of material and additional reinforcements on the second sheet of material until a tire is built.

  • Patent number: 10967673
    Abstract: A nonpneumatic tire includes a tread portion, an upper ring, and a plurality of spokes extending radially downward from the upper ring. Each spoke is configured to carry a load while in tension and while in compression. The upper ring and the plurality of spokes are part of a unitary component constructed of a single material. Each spoke terminates at a lower end having a spoke mount with an opening configured to engage a corresponding hub mount. Each spoke is under substantially no tension when the tread portion is not in contact with a ground surface and when each spoke mount is disengaged from its corresponding hub mount. Each spoke is under tension when the tread portion is not in contact with the ground surface and when each spoke mount is engaged with its corresponding hub mount.
