PNEUMATIC TIRE AND METHOD FOR MANUFACTURING SAME

摘要

An object of the present invention is to provide a production method of a pneumatic tire in which a generation of a tread groove crack is prevented while maintaining productivity and tire performance, and a pneumatic tire produced by this production method. The production method of a pneumatic tire having a tread composed of a predetermined rubber composition for a tread comprises: step A of molding an unvulcanized rubber composition for a tread to obtain a tread shape unvulcanized rubber composition provided with a concave profile, a step B of laminating the tread shape unvulcanized rubber composition obtained in the step A with other unvulcanized rubber compositions for tire member to obtain an unvulcanized tire, and a step C of vulcanizing the unvulcanized tire obtained in the step B in a vulcanization mold.
