Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing a tire, by and with which both of working efficiency and the commercial value of the product tire can be easily improved, while reducing the equipment cost.SOLUTION: A covered rubber layer 14 is cut and removed by using a cutter 35 while relatively rotating the cutter 35 and a vulcanized tire 11, so that a different-color rubber layer 13 is exposed. The cutting speed is made higher than the grinding speed by a grindstone to easily improve the working efficiency when the covered rubber layer 14 is removed. Since chips produced when the covered rubber layer 14 is cut are thin rubber ribbons and ribbon pieces, a large-scale dust collector is not required and the equipment cost can be reduced. Since the exposed surface of the different-color rubber layer 13 is a cut surface by the cutter 35, the exposed surface has a certain degree of glossiness and the commercial value can be improved.

Abstract: PROBLEM TO BE SOLVED: To prevent leakage of a pressurizing medium from a cavity inside without forming a green tire in larger volume or using an additional seal member in vulcanization of the green tire in a core vulcanizing mold.
SOLUTION: The green tire 5 formed in the same size (volume) as usual is thermally inflated to a predetermined volume, which allows to seal a gap part in a fitting section between a core 21 and a mold, by preheating in lump with the core 21 in a preheater beforehand vulcanizing in a tire manufacturing equipment. Meanwhile, the predetermined volume is set out, for example, by experimentally producing a finished tire in a vulcanizer and using a pressure value in a cavity 41 detected by a pressure sensor 42 at the time of trial production. The preheating condition of the preheater is set out based on the pressure value detected by the pressure sensor 42, and the preheater performs preheating until the green tire 5 thermally expands to the predetermined volume.
