a method of producing a light alloy wheel with a forging technique , aiming for producing the wheel having a large - diameter disk by use of a small - scale press device , comprising : heating an intermediate product that is formed by casting or forging and has a discoid and a cylindrical thick wall , which are to respectively become disk and rim at completion , to a plasticity temperature ; then , rotating the intermediate product with stopping of the rotating at interval of a predetermined angle ; pressing at least a portion of the to - be disk part by molds at time of said stopping , as to push out metal into recesses on the lower mold and to thereby form holes ; repeating of such rotating , stopping and pressing as to give a pattern on whole of the to - be disk part ; and further press processing and finish processing on the to - be disk and the to - be rim parts .
