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.

摘要： A high performance pneumatic radial tire (1) comprises a toroidal carcass (3), a tread (17) radially outside a crown portion of the carcass, a belt layer (10) interposed between the carcass and the tread and having the same width as the tread, and an auxiliary layer (16) arranged between the belt layer and the tread and covering the entire belt layer. Organic cords are buried substantially parallel to an equatorial plane of the tire in the auxiliary layer (16), and land portions (19) are defined between at least tow cicumferential main grooves (18) formed in the outer surface portion of the tread and between the circumferential main grooves and axially opposite edges of the tread. In the tire the rigidity of the tire corresponding to the locations overlapping the circumferential main grooves (18) is made smaller than that at portions corresponding the the land portions by, for example, forming the auxiliary layer from at least two auxiliary plies (21,22) comprising one auxiliary ply (21) located on a radially innermost side and covering the belt layer over an entire width thereof, and cutting at least a radially outermost auxiliary ply (12) at locations overlapping the circumferential main grooves among the auxiliary plies having portions overlapping the circumferential main groove.

摘要： A high-speed running pneumatic radial tire comprises a cylindrical crown portion, a pair of sidewall portions extending inward therefrom, a radial carcaas (7) extending from one of the sidewall portions through the crown portion to the other sidewall portion, and a belt (8) and a tread (9) successively superimposed on the crown portion outward in the radial direction of the tire. The tread has a plurality of rows of blocks (3) defined by a plurality of circumferential grooves (1a,1b) and by lateral grooves (2a,2b), and the belt (8) is comprised of at least two main cross-cord belt layers (8a) and an auxiliary belt layer (8b) arranged thereon. The auxiliary belt layer is formed by spirally winding a rubberized ribbon ply of heat-shrinkable cords (12) on the main belt layers (8a), in which an overlapped amount of the ribbon ply is made larger in a zone (B,C) of the tread substantially corresponding to a block row (3) than in a zone (A) of the tread substantially corresponding to a circumferential groove (1a,1b).
