A three-piece steel wheel rim for vehicle tires containing a front part, a center part, and a rear part. The front part and the rear part converge at the rear surfce of the center part and are bolted to the center part. Above the point of conversion, the rear part and the front part widen to form a V-shaped pocket which is partially closed by a rearwardly extending bulge on the front part. An O-ring is contained within the pocket. The center part may have a rearwardly extending support upon which the rear part may rest.
