Abstract
A method for vulcanizing a tire wherein firstly heating medium is blown toward a tire internal surface from a supply opening arranged at a position above an equator of the tire in a mold and secondary pressurizing medium is blown toward the tire internal surface from the supply opening, and an apparatus used therefor. By virtue of the method and the apparatus, in vulcanization, abnormal cooling at a lower bead of a tire is prevented and consequently a large temperature difference inside the tire is prevented, so that uniform vulcanization can be carried out to provide products having high quality. Further, prevention of the temperature difference makes it possible to shorten a time period required for vulcanization, to improve productivity, and to reduce energy loss.
