본 발명은, 제1 양태에서, 지면 접촉 트레드 부분 및 전단 밴드를 갖는 외부 환형 링과, 하나 이상의 스포크 디스크를 포함하는 비공기압 타이어 및 휠 조립체를 제공하며, 각각의 스포크 디스크는 전단 밴드에 연결되고, 각각의 스포크 디스크는 적어도 2개의 스포크를 갖고, 각각의 스포크는 제 1 레그 및 제 2 레그를 가지며, 제 1 레그 및 제 2 레그에는 보강재의 연속 스트립이 수용된다.
A non-pneumatic tire and wheel assembly (100) is disclosed comprising an outer annular ring (406) having a ground contacting tread portion (210), a shear band, and one or more spoke disks (400). Each spoke disk (400) is connected to the shear band and has at least two spokes (401). Each spoke (401) has a first leg and a second leg (402, 404). A continuous strip of reinforcement is received in the first leg (402) and the second leg (404). Also, a method of forming a reinforced spoke structure for a non-pneumatic tire and wheel assembly (100) is disclosed. The method comprises the steps: providing a first and second mold insert (610, 620), wherein the first and second mold insert (610, 620) are separated apart; winding a continuous strip of reinforcement around the first mold insert (610) and around the second mold (620) insert to form a reinforced structure; inserting the reinforced structure into a mold; and injection molding a liquid resin to form a spoke structure.
