Abstract

A motor vehicle wheel having hollow spokes and made of a light metal is produced in a casting process. In the hollow space, the wheel spokes have a dead core consisting of a metallic material in the form of a metal foam or of a closed shell-shaped element, which dead core remains in the hollow space after casting.
