This invention relates to the area of manufacturing disk wheels for railway vehicles with disks being integral with rim and having rail-engaging elements. A seamless rolled railway wheel 1 comprising a rim 2, a hub 3 and a disk 4 formed by inner 5 and outward 6 curved surfaces arranged in such a way, wherein a central line 7 of the radial section of said disk in the place of its conjugation with said rim 2 is shifted along the wheel axis 9 in relation to a central line 8 of the radial section of said disk in the place of its conjugation with said hub 3 toward said outward curved surface 6, the value of the shift of said central line 7 of the radial section of said disk 4. The invention provides the decrease of magnitude of the total values of inner stresses by optimal distribution of stresses into the wheel volume that will result in the increase of the wheel service life.
