Abstract: A wheel rim that includes a peripheral structure for receiving a tire, and a central structure for coupling with a hub of the vehicle. The peripheral structure includes, for each side of the wheel rim, a peripheral flange, a connecting wall on which the bead of the tire rests, and a connecting part. The peripheral structure includes a central well. The connecting part includes a first curved region which joins the central well, and a second curved region between the first curved region and the connecting wall. The second curved region has a convex profile from the side of the wheel rim with the tire, and includes a first curved surface joined to the connecting wall with a first radius of curvature, and a second curved surface between the first curved surface and the first curved region, with a second radius of curvature different from the first radius of curvature.
