A tire for a two-wheeled automotive vehicle, the tire comprising: a tread; a pair of sidewalls; a pair of beads; a carcass; and a band, wherein each sidewall extends almost inward from an end (Pe) of the tread in a radial direction, the beads are disposed inward of the sidewalls, respectively, in an axial direction, the carcass is extended on and between one of the beads and the other of the beads along inner sides of the tread and the sidewalls, the band is disposed between the tread and the carcass in the radial direction, and is layered over the carcass, the carcass includes a first carcass ply and a second carcass ply, the first carcass ply is turned up around the beads from an inner side toward an outer side in the axial direction, and the first carcass ply has a main portion and turned-up portions, the second carcass ply is disposed outward of the main portion in the radial direction, and is extended on and between one of the beads and the other of the beads, end portions of the second carcass ply extend inward in the radial direction, and ends of the second carcass ply are disposed between the beads and the turned-up portions, respectively, in the axial direction, ends of the turned-up portions are disposed between the main portion and the band, and the turned-up portions and the band are layered over each other, characterized in that a ratio of a width Wj to a width Wb is not less than 0.05 and not greater than 0.20, wherein the width Wb represents a distance from one of axial ends (Pb) of the band to the other of the axial ends (Pb) of the band, the width Wb is measured along the band, Wj represents a layered width over which each turned-up portion and the band are layered, and the layered width Wj is measured along a boundary between the turned-up portion and the band which are layered over each other. a tread; a pair of sidewalls; a pair of beads; a carcass; and a band, wherein each sidewall extends almost inward from an end (Pe) of the tread in a radial direction, the beads are disposed inward of the sidewalls, respectively, in an axial direction, the carcass is extended on and between one of the beads and the other of the beads along inner sides of the tread and the sidewalls, the band is disposed between the tread and the carcass in the radial direction, and is layered over the carcass, the carcass includes a first carcass ply and a second carcass ply, the first carcass ply is turned up around the beads from an inner side toward an outer side in the axial direction, and the first carcass ply has a main portion and turned-up portions, the second carcass ply is disposed outward of the main portion in the radial direction, and is extended on and between one of the beads and the other of the beads, end portions of the second carcass ply extend inward in the radial direction, and ends of the second carcass ply are disposed between the beads and the turned-up portions, respectively, in the axial direction, ends of the turned-up portions are disposed between the main portion and the band, and the turned-up portions and the band are layered over each other, characterized in that a ratio of a width Wj to a width Wb is not less than 0.05 and not greater than 0.20, wherein the width Wb represents a distance from one of axial ends (Pb) of the band to the other of the axial ends (Pb) of the band, the width Wb is measured along the band, Wj represents a layered width over which each turned-up portion and the band are layered, and the layered width Wj is measured along a boundary between the turned-up portion and the band which are layered over each other.
