A vehicle wheel e.g. for passenger cars, having a disc part connected to a rim part, the disc part, integrally formed form a sheet metal blank, has a central part with bolt holes for wheel bolts and a central hole for a vehicle hub, and a plurality of radially extending spoke arrangements for transmitting forces between the vehicle hub and the rim part. Each spoke arrangement is provided with a central web, merging on both sides into a radially extending side web, being bent outwards from the surface of the central web, and an edge web, bent back again relative to the side web, wherein the radially outer ends of the webs merge into a disc rim, being aligned parallel to the wheel axis, connecting all spoke arrangements to one another and delimiting ventilation holes. In order to provide, without structural drawbacks, steel vehicle wheels with an unequal number of bolt holes and spoke arrangements, an inner annular bead and an outer annular bead are formed in the central part, which beads are concentric with one another and with the disc rim, and a raised annular strip provided with the bolt holes is formed between the beads.
A vehicle wheel having a rim part and a disc part connected to the rim part, the disc part defining a wheel axis and having a central part having bolt holes and a central hole formed therein, the disc part having a plurality of radially extending spoke arrangements for transmitting forces between a vehicle hub and the rim part, wherein each spoke arrangement is provided with a radially extending central web, which merges on both sides thereof into a radially extending side web, bent axially outwards from a surface of the central web, and an edge web, bent back again axially relative to the side web thereby giving each of the spoke arrangements at least in part a generally U-shaped cross-sectional profile, wherein radially outer ends of the central webs and of the side webs merge into an encircling annular disc rim which connects all the spoke arrangements to one another, the encircling annular disc rim forms a connecting part for a connection between the rim part and the disc part, wherein the encircling annular disc rim and the edge webs of adjacent spoke arrangements define ventilation holes, wherein the number of spoke arrangements and the number of bolt holes is unequal, and a quotient of the number of spoke arrangements to bolt holes does not give a natural number, and wherein an inner annular bead and an outer annular bead are formed in the central part, which inner and outer annular beads are concentric with one another and with the encircling annular disc rim and between the inner and outer annular beads there is formed a raised annular strip in which the bolt holes are formed, wherein the encircling annular disc rim, over an entire axial extension thereof, is aligned parallel to the wheel axis and wherein the encircling annular disc rim in a region thereof which adjoins the ventilation hole has an oblique front edge.
