lightweight rims for motor vehicles are increasingly replacing steel rims for motor vehicles. In order to achieve the required strength, the rim body is configured with a thick wall and is heavy. A weight reduction is desired, as rims in their capacity of unsuspended masses must be as light as possible, in order to maintain the contact with the ground. Light metal rims with varying constructions and designs are known in prior art. The inventive lightweight rim is characterised by a highly symmetrical and particularly delicate construction, which requires a small amount of material, but guarantees a high strength by the high degree of crosslinking. The spokes fall into two categories, radial spokes and ring spokes. The radial spokes have a high aspect ratio in terms of the width of the ribs to their depth with an intersecting overlay of the radial spokes with the ring spokes, so that all the spokes support one another reciprocally. Especially advantageous is a configuration of 16 radial spokes and 6 ring spokes. The form of the lightweight rim thus resembles that of the diatom Arachnoidiscus.
