A method of manufacturing a wheel rim for a motor vehicle, including cutting off a section of an extruded cylindrical tube to produce a hollow cylindrical rim blank, and subjecting the blank to two successive deformation steps. During the first step, only the central section of the blank is deformed radially inwardly, the diameter of the end sections remaining substantially unchanged. In the second step, only the edge portions of each end section are deformed radially outwardly, so that the region between each edge portion and the central section is unchanged in diameter. Also, the outermost part of each edge of the blank is bent into a U-shape. The rim is then gauged to finish it. The first deformation step is performed by a pair of cooperating rollers having central sections shaped to deform the central section of the blank. The end sections of the rollers are spaced apart to accommodate the end sections of the blank, the spaces being open at the sides of the rollers to permit free endwise flow of the rim blank outwardly from between the rollers.
