PROBLEM TO BE SOLVED: To sufficiently reduce tube force variation in the radial direction of an individual tire. SOLUTION: In an average waveform recording process, the RFV waveform component of the molding factor at every molding machine and the RFV waveform component of the vulcanization factor at every molding machine are obtained to be recorded on an electric computer 16. In a waveform synthesizing process, the RRO waveform of a green tire 10 is substituted with a RFV waveform component and the RFV waveform components of the molding factor and the vulcanization factor are superposed thereon to obtain an RFV synthesized waveform. In a selection process, the peripheral position of the green tire 10 minimizing the amplitude of the RFV synthesized waveform and that of a vulcanizing mold are selected and, in a vulcanizing process, the green tire 10 is arranged in the vulcanizing mold on the basis of the peripheral positions selected in the selection process to be vulcanized. By this constitution, the force vaiation in the radial direction of the tire is sufficiently reduced.
