A disc wheel comprising: an asymmetrical rim having first and second axially spaced bead seats separated by a well and a ledge between the first bead seat and said well, and a dish-shaped disc having its edge portion T-butt welded to the radially inner surface of the rim at a point adjacent to the transition from the first bead seat to the ledge such that the side of said edge portion closer to the well is located within a distance B/5 of the transition between the ledge and the first bead seat (where B is the minimum bead seat length of the standard to which the rim is made), and wherein the center line of the edge portion of the disc, when viewed in radial section, makes an angle of between 0°and 30°with a plane perpendicular to the rotary axis of the wheel and passing through the intersection of the center line and said inner surface to which the edge portion is welded, the edge portion extending away from the welded joint in a direction so as to lie partly within the first bead seat.
