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.

Embodiments of the invention include a mold for forming a tire tread. The mold includes a tongue forming portion at an end of a tread forming portion. The tongue forming portion has a substantially constant thickness, except for a portion at an end of the tongue forming portion having a thickness greater than a thickness of a remainder of the tongue forming portion.

A method for vulcanizing a tire with a tire vulcanization machine having closing force unit for the treatment space of the tire vulcanization machine. The closing force unit having a base plate and at least one linear drive for the displacement and force application of a mold pressure plate, wherein the at least one linear drive is an integral part of the base plate so that a compact and stringent structure of the closing force unit is supported.
