Abstract

A method for producing a motor vehicle rim made of aluminum or an aluminum alloy for a motor vehicle wheel. The motor vehicle rim has a rim base delimited on opposite sides by an outer horn and an inner horn, a hub with a central recess and a hole circle and a rim center connecting the rim base and the hub to one another and acting eccentrically on the rim base in longitudinal section. The motor vehicle rim is produced in one piece and continuously in a casting mold by vacuum die casting of a casting material, wherein the motor vehicle rim has a small wall thickness of at most 15 mm at least in some regions and/or a curvature with a small radius of curvature of at most 4 mm.
