摘要： A pneumatic tire comprising a tread portion (4), a pair of sidewall portions (6) and a pair of bead portions (8) is manufactured by conducting the venting in a portion of a green tire (3) placed in a vulcanization mold (1) prior to vulcanization and corresponding to the sidewall portion in at least one place in a radial direction of the tire during the vulcanization. The vulcanization mold (1) comprises a tread ring (5) comprised of plural segments (5a) reciprocatively displacable in a radial direction and contributing to shape the tread portion (4), a pair of side portion rings (7) contributing to shape a pair of sidewall portions (6), and a pair of bead portion rings (9) each contributing to shape the bead portions (8), in which a venting gap (11) is arranged in at least one place of the side portion ring (7) in the radial direction so as to extend over the full circumference of the ring and pass through the ring from the inside toward the outside thereof.
