Provided is a tire for a two-wheeled motor vehicle, the tire being configured so that driving stability performance can be improved and so that the uneven wear of the tread can be reduced. A tire for a two-wheeled motor vehicle has a carcass (2) used as the framework of the tire and comprising one or more radial carcass plies toroidally extending between a pair of beads, and the tire comprises, in sequence on the outer peripheral side of the crown region of the carcass (2), a belt layer (3), a single auxiliary belt layer (4), and tread rubber. The peripheral width (PB) of the auxiliary belt layer (4) is set to be greater than the peripheral width (PA) of the belt layer (3). The cords of the auxiliary belt layer (4) extend from both ends of the equatorial region (PE) of the tire, the equatorial region (PE) including the equatorial plane (E) of the tire, toward 1/4-points in the direction in which the tilt angle of the cords relative to the circumferential direction of the tire decreases gradually, the tilt angle of the cords at the 1/4-points being in the range of 60 degrees to 85 degrees, inclusive, the 1/4-points being each located at a distance which corresponds to 1/4 the peripheral width (PB) of the auxiliary belt layer (4) and which is measured along the periphery of the auxiliary belt layer (4) from the equatorial plane (E) of the tire.
