Abstract
A method for fabrication of a non-pneumatic tire and wheel assembly incorporates a tire tread and a conventional vehicle wheel with an elastomer tire body element formed by introducing elastomer into mold elements with a center plug and releasably carried chamber forms to provide integral wall elements extending radially inward from the tire body element for sealing engagement with the wheel. The tire body element includes multiple concentric layers with alternating spokes formed with strut and aperture dimensions in the mold elements and mating rubber cast blocks adapted for the desired spoke design. After curing, the tire assembly is mounted on the conventional wheel with conventional mounting tools to deform the integral side walls and a pneumatic chamber formed by the side walls is inflated.
