Abstract: A method of manufacturing a run-flat the capable of manufacturing a run-flat tire with excellent uniformity due to its less occurrence of eccentricity than in conventional methods by simple facility and steps. The method comprises a step for disposing an inner liner rubber (19), reinforcement rubber members (18) reinforcing side wall parts on both sides, and a carcass ply (14) at the prescribed outer peripheral positions of a molding drum, a step for disposing a pair of first beads (1a) and bead fillers (12) and toroidally deforming the inside of the first bead (1a), a step for curling up and stamping the end part (14b) of the carcass ply (14), a step for stamping rubber members (13a) and (13b) forming annular swelled parts on the sides of the bead filler (12) of a toroidal formed product, and a step for forming second beads (1b) by spirally stamping cords (BW) on the formed product while rotating the formed product after that stamping about the axis thereof.
