A vehicle wheel made of light metal and consisting of a hub and a rim surface is produced by a process comprising the steps of producing a substantially discshaped crude billet from an extruded bolt or a similar rounded solid metal body, heating of a crude billet to a hot rolling temperature and subsequently orbitally rolling the crude billet so as to obtain a rotationally symmetric preformed material, splitting off of the outer portion of the preformed material, and afterwards forming a rim surface by spinning the outer, split-off rim portion. As an alternative, the preformed material after orbital rolling and before splitting can be compressed or cold forged in order to obtain a desired specified design for the hub of the wheel.
