    Abstract: A pneumatic radial tire comprises a carcass comprising an outer carcass ply made of cords having a first heat-shrinkage-percentage K1 and an inner carcass ply is made of cords having a second heat-shrinkage-percentage K2 different from the first heat-shrinkage-percentage K1, and the cord tension of the inner carcass ply is smaller than the cord tension of the outer carcass ply. A method of making the tire comprises steps of making the outer carcass ply of cords having a first heat-shrinkage-percentage K1, making the inner carcass ply of cords having a second heat-shrinkage-percentage K2, wherein the first heat-shrinkage-percentage K1 at 150 degrees C. is 120 to 160% of the second heat-shrinkage-percentage K2 at 150 degrees C., and heating and vulcanizing a raw tire to heat-shrink the outer carcass ply cords in a larger degree than the inner carcass ply.

    Abstract: A method of manufacturing a radial tire is disclosed, wherein a tread ring is formed separately from a tier main body by the sue 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 radiallly 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.
