摘要:
A pneumatic tire 1 having improved uniformity and durability and including a toroidal carcass 6 extending from a tread portion 2 to each of bead cores 5 in bead portions 4 through sidewall portions 3, a belt layer 7 disposed radially outward of the carcass 6 in the tread portion 2, and a cushion rubber 9 having an approximately triangular cross section disposed between the carcass 6 and each of axial edge portions 7E of the belt layer 7, and a method for producing the same, wherein the cushion rubber 9 is made from a strip laminated body formed by circumferentially and spirally winding a first ribbon-like unvulcanized rubber strip and a second ribbon-like unvulcanized rubber strip having a different composition from that of the first rubber strip.
