A method and a means for the manufacture of a wheel construction (2) of plastic material for vehicles or similar, which comprises a number of spokes (2A-2H), a hub (2J) and a rim (2I) together constituting an integrated unit. By means of the invention it is made possible to manufacture a wheel construction, the strength property of which is high. The plastic material is injected in a mould (1), the cavity (7) of which exhibits a form corresponding to the one of the desired wheel construction, the design of the wheel being chosen to comprise an even number of spokes (2A-2H). The inlets (3-6) are located at such points near to every second one of the spoke portions (2A-2H) forming part of said mould (1), that the zones (7'), where the flows of material join each other, will be located near to points, where the spoke portions (2B, 2D, 2F, 2H), free from inlets, blend into the rim (2I).
