A non-pneumatic tire and rim assembly, the assembly comprising:
- a non-pneumatic tire including:
- a ring;
- a circumferential tread disposed about the ring;
- a plurality of spokes extending radially downward from the ring,
- wherein each spoke terminates at a lower end defined by an axially extending member,
- wherein each spoke includes a reinforcement at least partially wrapping around the axially extending member,
- wherein the reinforcement is a sheet of reinforcement material;
- a rim including a plurality of mounts, each mount being configured to receive the axially extending member of a corresponding spoke,
- wherein the reinforcement includes a first reinforcement sheet with a first end terminating below the axially extending member and a second reinforcement sheet with a second end terminating below the axially extending member.
A method of making a non-pneumatic tire, the method comprising:
- providing a ring;
- providing a plurality of elongated members;
- arranging the elongated members inside the ring, such that each elongated member extends in an axial direction relative to the ring;
- providing a first ribbon of reinforcement material and a second ribbon of reinforcement material;
- and
- wrapping the first ribbon of reinforcement material and the second ribbon of reinforcement material around each of the elongated members, such that each of the first ribbon of reinforcement material and the second ribbon of reinforcement material terminates below the elongated member.
A non-pneumatic tire comprising:
- a ring;
- a circumferential tread disposed about the ring;
- a plurality of support structures extending downwards from the ring, wherein an end of each support structure includes an axially extending member, and wherein each support structure includes a sheet of reinforcement material extending along a length of the support structure and terminating below the axially extending member.
