A pneumatic tire comprising: a carcass extending between bead portions (4, 4) through a tread portion and sidewall portions (3, 3), a belt layer comprising a belt ply disposed radially outward of the carcass in the tread portion and a band layer comprising a band ply disposed radially outward of the belt layer; the belt ply being formed of a plurality of narrow rectangular ply pieces spaced from one another in a circumferential direction of the tire, each of the rectangular ply pieces having a certain length and comprising an arrangement body of a plurality of belt cords covered with rubber; and the band ply being formed of a narrow ribbon shaped ply tape wound spirally in the circumferential direction of the tire, the ply tape comprising at least one band cord covered with rubber, characterized in that the band cord comprises a composite cord that comprises a first strand and a second strand which are twisted together, wherein the first strand is made of high modulus organic fibers, and wherein the second strand is made of low modulus organic fibers and is finer than the first strand, wherein as the high modulus organic fibers, aramid fibers, polyethylene terephthalate fibers and polyethylene naphthalate fibers can be employed, and as the low modulus fibers, nylon fibers, polyester fibers and vinylon fibers can be employed, wherein the tread portion is provided with circumferentially and continuously extending main grooves and a land portion separated by the main grooves, and a band cord density of a radially inner region of the main grooves is smaller than a band cord density of a radially inner region of the land portion. a carcass extending between bead portions (4, 4) through a tread portion and sidewall portions (3, 3), a belt layer comprising a belt ply disposed radially outward of the carcass in the tread portion and a band layer comprising a band ply disposed radially outward of the belt layer; the belt ply being formed of a plurality of narrow rectangular ply pieces spaced from one another in a circumferential direction of the tire, each of the rectangular ply pieces having a certain length and comprising an arrangement body of a plurality of belt cords covered with rubber; and the band ply being formed of a narrow ribbon shaped ply tape wound spirally in the circumferential direction of the tire, the ply tape comprising at least one band cord covered with rubber, characterized in that the band cord comprises a composite cord that comprises a first strand and a second strand which are twisted together, wherein the first strand is made of high modulus organic fibers, and wherein the second strand is made of low modulus organic fibers and is finer than the first strand, wherein as the high modulus organic fibers, aramid fibers, polyethylene terephthalate fibers and polyethylene naphthalate fibers can be employed, and as the low modulus fibers, nylon fibers, polyester fibers and vinylon fibers can be employed, wherein the tread portion is provided with circumferentially and continuously extending main grooves and a land portion separated by the main grooves, and a band cord density of a radially inner region of the main grooves is smaller than a band cord density of a radially inner region of the land portion.
