ABSTRACT:
A wheel disc and method of manufacture wherein disc blanks are punched from a continuous length of strip material in an enchelonned nested pattern so as to minimize stock scrap and wastage. The disc blanks are substantially flat and have a peripheral edge defined by a series of concentric convex crowns separated from each other by concave recesses. The disc blanks are each formed to a final cross sectional configuration which optimizes the relationship of disc strength to weight. The disc is welded into a drop center wheel rim to provide a wheel assembly for pneumatic tubeless tires.
