METHOD OF MANUFACTURING PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a pneumatic tire having the reduced dynamic unbalance and high durability. SOLUTION: This method of manufacturing the pneumatic tire is as follows: (1) first, a side wall rubber 17 is laminated on the outside of a carcass ply 12, and the diameter of a molding drum 1 is expanded. (2) A belt layer 19 and a tread rubber 18 are laminated on the outside of a corresponding position to a crown part of the carcass ply 12. (3) A green tire G is molded and an annular projecting part 22 is formed by laminating a strip rubber member 21 to a buttress part B of the green tire G and the green tire G is vulcanization-molded using a mold to obtain the pneumatic tire with a projection formed in the buttress part.
