Abstract

A light-metal strip wheel, in particular for motor vehicles, which includes a wheel disk and a rim. The wheel disk comprises two wheel-disk parts each having a ventilation hole. The ventilation holes have necks that when pressed into one another, secure together the two wheel-disk parts with the two parts separated from one another in the region surrounding the ventilation holes, while coming to rest on one another in a hub region. The space between the two wheel-disk parts in the region surrounding the ventilation holes increases the stiffness of the strip wheel so that the wheel is suitable for accommodating large loads.
