Abstract
A multi-part vehicle wheel includes a rim spider and a rim which are mutually connected by screwing devices. For connection by way of the screwing devices, the rim spider has ring surfaces which are placed flush on the rim. So that precise positioning of the metal foam core can take place, this metal foam core has core marks or needle cushions. For sealing off the hollow space of the spoke of the rim spider, which is filled with metal foam, a sealing strip or a sealing ring is arranged between the rim and the rim spider and is held in a clamped-in manner when the wheel parts are connected.
