A method for producing a drop centre rim and to a drop centre rim for vehicle wheels of commercial vehicles. The rim has a plurality of zones, which form an inner rim flange and an outer rim flange, an inner steep-tapered bead seat and an outer steep-tapered bead seat and a rim drop centre with a drop centre base, an inner drop centre flank and an outer drop centre flank between the steep-tapered bead seats, wherein one of the zones is provided as a disc attachment region for a wheel disc, and the drop centre rim has at least one partial zone with a reduced wall thickness relative to the other zones. It is envisaged that at least one of the steep-tapered bead seats, preferably both steep-tapered bead seats, has/have a section with a wall thickness reduction of more than 20% relative to the wall thickness in the zone provided as the disc attachment region, wherein the wall thickness reduction is produced during one of the profiling steps.

A process for manufacturing a light-alloy hybrid wheel, implements the following separate operation phases: making a flange with an internal profile capable of constituting a tire bead seat; making a rim with, on one side, an outer profile capable of constituting a tire bead seat and, on the other side, a circular flank for assembly with a part of the flange; and assembling the flange with the rim, at the seat of said flange and the circular flank of the rim. The rim is made according to the following consecutive operations: an operation of manufacturing a circular flank; then an operation of expanding said circular flank to the size of the final rim in a single step; then an operation of cold or hot flospinning of said circular flank so as to obtain the rim in the final shape and profile thereof, comprising a shoulder only on the side that will not be welded to the flange.
