摘要： In a method for controlling a tire vulcanization of a vulcanizing apparatus, an initial green tire temperature is measured before vulcanization and a tire temperature during vulcanization is estimated on the basis of the thus measured initial tire temperature. In addition, a sum of products of vulcanizing rates derived from the thus estimated tire temperature is calculated so as to stop the tire vulcanization when the sum of products of vulcanizing rates becomes equal to a predetermined value. Therefore, the vulcanizing rate controlling can be performed in an easy and accurate manner without measuring the tire temperature during vulcanization, and thus a trace of a thermometer insertion is not remained on the vulcanized tire surface.
