ABSTRACT A device for manufacturing vehicle wheels having a rim which is wreath-shaped in cross section surrounding a cast wheel body is such that at least one die wall delimits the mould to be filled with cast metal; the prefabricated rim is laid between facing surfaces of a die plate and a centre plate, with the result that the die faces and the rim form the outer contours of the wheel body when the mould space between the die faces and rim is filled with molten metal which is introduced under pressure, the rim itself is held by a clamping ring which can be removed in two pieces from the die assembly; a device for spraying a cooling medium onto the rim is provided on or in the clamping ring; the rim features on its inner face a central strut which is T-shaped in cross section, and on both sides of this side struts which are inclined outwards, the free ends of the side struts are displaced by the surface of the die plates.
