Abstract:
The purpose of the present invention is to efficiently vulcanize a green tire. This tire vulcanizing method and tire manufacturing method for vulcanizing a green tire 2A formed on an outer surface 11s of a rigid core by putting in a vulcanizing mold together with the rigid core 3A. The method comprising: a preheating step S1 of preheating the rigid core accompanied by green tire 3A using a preheating device 5 arranged adjacent to the vulcanizing mold 4 prior to vulcanizing; a vulcanizing step S3 of vulcanizing the green tire accompanied by preheated rigid core 3A using the vulcanizing mold 4; and a cooling step S5 of cooling the rigid core accompanied by vulcanized tire 3B which has a vulcanized tire 2B made by vulcanizing the green tire 2A by use of a cooling device 6.
