摘要： A pneumatic tire having an aspect ratio of not more than 55% and comprising: an axially protruding rib provided on each side of the tire to overhang a flange of a wheel rim; a carcass extending between bead portions through a tread portion and sidewall portions; a belt disposed radially outside the carcass; a tread rubber disposed radially outside the belt to define the ground contacting surface of the tire; a sidewall rubber disposed on each side of the tire and extending from the tread portion to the rib along the axially outside of the carcass; a clinch rubber disposed on each side of the tire and extending from the bead portion to the rib along the outer surface of the tire; and a wing rubber disposed axially outside the sidewall rubber and extending from the tread rubber to the rib along the outer surface of the tire, the wing rubber being softer than the tread rubber. In a tire meridian section, in a region defined between 45% and 70% of the tire section height, every boundary line between rubber layers which include the tread rubber, sidewall rubber, clinch rubber and wing rubber at least, intersects neither the outer surface of the tire nor the outside of the carcass.

摘要： A method of manufacturing a radial tire is disclosed, wherein a tread ring is formed separately from a tire main body by the use of a tread ring forming apparatus. The radial tire comprises a belt having a camber and a band wound thereon. The tread ring is an annular assembly of a raw belt, a raw band wound thereon and a raw tread rubber. The tread ring forming apparatus comprising a belt drum made up of segments defining the drum circumference. In a cross section including the belt drum axis, the radially outer surface of each segment is a straight line parallel to the axis. In a cross section normal to the belt drum axis, the radially outer surface is an arc having one radius substantially equal to one half of the drum diameter, but the drum circumference is decreased in the belt edge portion than the central portion by increasing gaps between the segments.

摘要： A method for manufacturing a pneumatic tire with a noise damper on the inside of the tread portion, comprises the steps of: building a raw tire on an annular tire building core; placing the raw tire within a vulcanizing mold together with the core; and heating the raw tire in the mold. The tire building core has a molding face for molding an inner surface of the tread portion. The molding face is provided with a groove extending in the tire circumferential direction. In the step of building the raw tire, an expandable damper material is placed in the groove. During heating the raw tire to be vulcanized, the damper material expands in the groove, whereby the expanded material forms the noise damper integrated into the radially inside of the tread portion.
