Abstract
Vehicle wheel comprising a rim part and a disc part formed from a one-piece sheet metal blank and including a central portion with bolt holes and a plurality of radially extending spoke arrangements merging into a disc edge delimiting together with the spoke arrangements ventilation apertures which extend over the region between the edge webs and the disc edge. In order to create steel wheels with four-hole fixing in which high strength and stiffness are achieved the number of spoke arrangements and of bolt holes is four and these are in each case arranged mirror-symmetrically with respect to a common radial line, with the width of each spoke arrangement narrowing radially towards the outside and each ventilation aperture extending in the circumferential direction over an arc length of more than ⅙ of the circumference of the disc part. Further, each ventilation aperture is having on a radial line a maximum radial clear width which is equal to or preferably greater than the radial width of the metal portion of the disc part on the same radial line.
