A method of manufacturing a solid wheel rim having a wheel-rim flange at one end of a wheel rim base and a spring-ring groove at an opposite end of the base, from a rolled and a longitudinally welded sheet-metal ring of a predetermined inner diameter having a reduced wall thickness over at least a part of its length, includes the contraction of a portion of the ring to produce an annular groove zone having an inner diameter of a first predetermined size, an enlarged zone having an inner diameter greater than the inner diameter of such predetermined size, and a tapered zone located between the annular groove and enlarged zones, the wall thickness of the ring being reduced during a pressing operation, and the spring-ring groove as well as the wheel-rim flange being formed during a rolling operation.
