METHOD FOR MANUFACTURING PNEUMATIC TIRE

PROBLEM TO BE SOLVED: To improve uniformity while maintaining appearance quality of a tire. SOLUTION: Immediately before a shaping step S3, a heating step S4 for heating a uniformity correcting region R of a wind B at 30 to 70 deg.C is provided. The region R is a range of 1/6 to 1/3 of the overall p...

Zusammenfassung:	PROBLEM TO BE SOLVED: To improve uniformity while maintaining appearance quality of a tire. SOLUTION: Immediately before a shaping step S3, a heating step S4 for heating a uniformity correcting region R of a wind B at 30 to 70 deg.C is provided. The region R is a range of 1/6 to 1/3 of the overall periphery of the tire at the maximum valley K of a primary waveform Y1 as a center by obtaining a plurality of RFV mean curves Y of a reference tire obtained by vulcanizing a raw tire of the same lot in which the step S4 is not provided.
