Abstract
A rim for a motor vehicle wheel with several through-openings which are arranged on a concentric aperture circle of the wheel circumferentially with respect to a wheel brake and which form air inlet and outlets. The openings are constructed semi-circularly shaped and include an arcuately shaped outer boundary surface and an arcuately shaped inner boundary surface. The outer boundary surface is formed each by a section of the aperture circle and the further inner boundary surface adjoins this section. The arc of this boundary surface extends up to a concentric inner circle of the wheel which has a smaller radius.
