Abstract: A method of manufacturing an aluminum alloy wheel, comprising the steps of producing an elongated strip of alloy blank with a desired cross-section by squeezing an alloy material, pre-curving the two ends of said blank into arcs, placing one end of said blank between an upper main roller and a lower main roller of a rolling machine to hold said blank, when said blank is being held by said upper main roller and said lower main roller and being driven back and forth along the longitudinal direction, approaching two auxiliary rollers of said rolling machine toward the two sides of said upper main roller to push said blank, so that said blank follows the curve established by a holding point between said upper main roller and said lower main roller and pushing points of said auxiliary rollers to progressively coil into the shape of the desired aluminum alloy wheel.
