Abstract

This disclosure includes methods and apparatus for forming a non-pneumatic tire carcass comprising an inner hub, an outer band, and a plurality of spokes. The method includes arranging the inner hub, the plurality of spokes, and the outer band to form a curing assembly arranged in a first arrangement within a forming apparatus, where the inner hub is arranged concentrically within a radially inner annular side of the outer band and the plurality of spokes are arranged between the outer band and the inner hub. The plurality of spokes are forced in opposite radial directions from the first arrangement and to a second arrangement, where each spoke of the plurality of spokes is forced in a curing position against the inner hub and towards the outer band in a curing arrangement. The plurality of spokes are then cured to each of the inner hub and outer band.
