Abstract

A wheel for a motor vehicle includes cavities in a spoked rim structure. These cavities are provided with a removable sand core or with a remaining core, for example, made of metal foam. A rim, or a rim and a rim flange, may be connected with the spoked rim structure, so that a two-part or a three-part wheel can be produced in a simple manner.
