1. A method of making a nonpneumatic tire, the method comprising:
providing a forming jig having a plurality of members extending therefrom,
wherein the plurality of members include a first set of members defining a first circle having a first diameter, and
wherein the plurality of members include a second set of members defining a second circle having a second diameter larger than the first diameter,
providing a ply of flexible material, the ply of flexible material having a width equal to a final width of the nonpneumatic tire;
wrapping the ply of flexible material about the plurality of members to form an annular shape,
wherein the wrapping includes wrapping the ply of flexible material from a first one of the first set of members to a first one of the second set of members, and
wherein the wrapping further includes wrapping the ply of flexible material from a second one of the second set of members to a second one of the first set of members;
wrapping the ply of flexible material over itself multiple times in a circular direction to form an outer hoop configured to receive a circumferential tread;
curing the ply of flexible material; and
removing the ply of flexible material from the jig.
