(57) [Problem] To provide a tire molding method that improves tack and vulcanization adhesion at the time of molding a joint surface (splice surface) of a tire tread. SOLUTION: When joining one end and the other end of a strip made of an unvulcanized rubber composition to form an annular tire tread, a cutting angle α is 20 degrees by a blade heated to 140 ° C. to 260 ° C. Cutting speed 20mm so as to be ~ 60 degrees A method for forming a tire, characterized in that both end portions of the strip are cut transversely at a rate of 1 mm / sec to 95 mm / sec to form a joint surface, and then the joint surfaces are bonded to each other. |
