The invention relates to a wheel structure for an automobile having a wheel rim (10), a central part (50, 60) and spoke elements (20), wherein the spoke elements (20) are connected to the wheel rim (10) and can be individually connected to the central part (50, 60), said spoke elements (20) are provided with through-holes for wheel screws (40) or bolts and the central part (50, 60) is provided with holes for screwing in or pushing through same wheel screws (40) or bolts. The through-holes of the spoke elements (20) form a first hole circle and the holes in the central part form a second hole circle. According to the invention, the diameter of the first hole circle is smaller than the diameter of the second hole circle if the spoke elements (20) are not connected to the central part (50, 60), and the diameter of the first hole circle corresponds to the diameter of the second hole circle if the spoke elements (20) are also connected to the central part. During and as a result of the connection of the spoke elements (20) to the central part (50, 60), the diameter of the first hole circle is extended to correspond to the diameter of the second hole circle, wherein a pretension is produced in the wheel structure which has a favourable effect, inter alia, on the stability of the connection between the spoke elements (20) and the wheel rim (10). |
