Patent ID: 7774938

Claim:
A method of producing a weight-optimized pneumatic tire rim having rotationally-symmetrically partially different wall thicknesses, the steps comprising: providing a tube section having a first wall thickness and two terminal ends; leveling the first wall thickness starting from the two terminal ends over a defined rotationally-symmetrical area thereby forming two flanks by precontouring, each of the flanks including one of the terminal ends and each flank having a second wall thickness, and pushing tolerance-caused excess material of the flanks into a well base zone between the two flanks, the well base zone having a third wall thickness; contouring the flanks by pressure rolling while drawing each of the flanks toward their respective terminal ends and reducing the second wall thickness of each of the flanks with respect to the third wall thickness of the well base zone, the contouring beginning outside the well base zone; and wherein the second wall thicknesses vary according to predetermined measurements.
