    摘要: A mold for a pneumatic tire with an inflatable bladder is disclosed with a pair of axially spaced bead portions each with a bead bottom surface extending from a bead toe toward the axially outside of the tire. The bladder is disposed inside the green tire in the mold and inflated to press the green tire against the inside of the mold. The mold comprises a pair of bead rings and each bead ring is provided with a bead bottom molding face for molding said bead bottom surface. Each bead ring is provided radially inside the bead bottom molding face with a protrusion protruding axially inwardly from the axially inner end of the bead bottom molding face so that the axial extent of the protrusion from the axially inner end of the bead bottom molding face is in the range of from 0.05 to 0.4 times the axial distance between the axially inner ends of the bead molding faces.
