<P>PROBLEM TO BE SOLVED: To provide a production method of a tire which controls difference of vulcanization degree due to a part location and reduces generation of bubbles, etc. <P>SOLUTION: A semi-vulcanized tire 22 is taken out from a vulcanizing machine 10 when vulcanization has sufficiently progressed on the surface of a raw tire 20 (at the time of ending of pre-vulcanization). Then, the semi-vulcanized tire 22, once opened to atmosphere outside of the vulcanizing machine 10, is again moved into a pressurizing vessel 30 and is provided with gas pressure or liquid pressure from surrounds, so that vulcanization of an inner part (a most-delayed part) of the semi-vulcanized tire 22, which is not sufficiently vulcanized yet, is made to progress. <P>COPYRIGHT: (C)2012,JPO&INPIT |
