PROBLEM TO BE SOLVED: To provide a vulcanizing method for pneumatic tire which continuously prevents a vent cut from occurring when an unvulcanized tire is vulcanization-molded and enables vulcanizing troubles to be reduced. SOLUTION: On the external surface of the unvulcanized tire, a mixed liquid of a denatured silicone oil and an alkoxy silane is applied. Then, the unvulcanized tire is inserted in a vulcanization die having vent holes, and is vulcanization-molded. Thus, the film of the mixed liquid is formed on the surface of the vent holes of the vulcanization die, and at the same time, the unvulcanized tire on which the mixed liquid has not been applied is vulcanized by using the vulcanization die on which the film has been formed by this vulcanizing method. The denatured silicone oil has a silanol group on the end, and of which the molecular weight is 10,000 to 100,000. COPYRIGHT: (C)2010,JPO&INPIT |
