A wheel rim (1) with a circumferential surface (4) has a tire that can be mounted thereon. A sound-absorbing material (6) rests on the wheel rim (1) and is arranged underneath a surface-forming structure (8) extends transversely over the entire width of the sound-absorbing material. A recessed receptacle (5) for the sound-absorbing material (6) is formed in the circumferential surface (4). The upper side (8a) of the surface-forming structure (8) coincides with the predetermined course (7) of the circumferential surface (4).
