PROBLEM TO BE SOLVED: To provide an expandable tire curing bladder for shaping a pneumatic tire. SOLUTION: The tire curing bladder in an unmounted and relaxed state has a pair of annular beads facing each other, and also has a body which further has a central part, sidewall parts and the shoulder parts inserted between the central part and the sidewall parts. The body is formed of an outer contour surface and an inner contour surface, and the central part has a bladder gauge becoming large up to the maximum value in the axial direction in the shoulder parts. The bladder gauge in the shoulder parts is smaller than the maximum value and becomes large up to the beads from the shoulder parts. COPYRIGHT: (C)2009,JPO&INPIT |
