Claim:
A method for producing a run-flat support body in the form of a shell-type, annular metal body with an undulated annular supporting surface for run-flat vehicle wheels, comprising the steps: providing a rectangular metal blank with a long side adapted to the circumference of the annular body and a narrow side adapted to the width of the annular body, Bending the metal blank along the long side to form an open ring, Welding the ends of the open ring to form a closed annular blank, Profiling the annular surface circumferentially to impart a cross-sectional undulated profile using a pressure rolling method, Mounting detachably interconnectable connecting elements whose faces lie opposite one another to the profiled annular blank, and Cutting the annular blank between the connecting elements to produce the mountable shell-type annular body with the undulated annular supporting surface.
