PURPOSE: To improve the operating efficiency of a mold switching station without causing a defect at a tire by vulcanizing the tire by setting the relationship between the molding pressure of the station at the time of closing the mold and the internal pressures of the tire at the time of the period where the tire arrives at the station, after the arrival and after the end of the vulcanization to the specific relations. CONSTITUTION: A tire vulcanizing facility has vulcanizing stations 1a, 1b for aligning and vulcanizing a plurality of sets of tire molds Ma, Mb,..., mold switching stations 2a, 2b for removing the vulcanized tire and inserting an unvulcanized tire, and conveying trucks 3a, 3b for conveying the molds Ma, Mb,... between the stations 1a, 1b and 2a, 2b. When the molding pressure of the station 2a at the time of closing the mold is P, the internal pressure of the tire from the conveyance by the truck 3a after closing the mold to the arrival at the station la is P2 , the internal pressure of the tire after the arrival is P3 and the internal pressure of the tire after the end of the vulcanization is substantially the atmospheric pressure P0 , the tire is vulcanized by setting the relationship of the internal pressures of the tire to P0 <P1 <P2 <P3 . |
