Abstract
In a tire 2 for a two-wheeled automotive vehicle, a carcass ply 24 is extended on and between one bead 8 and the other bead 8 along inner sides of a tread 4 and sidewalls 6, and includes a main portion 24a and turn-up portions 24b, which are formed by the carcass ply 24 being turned up around the beads 8 from an inner side toward an outer side in an axial direction. An outer end Pp of each turn-up portion 24b is positioned outward of a tread end Pe in a radial direction. A band 14 is positioned between a belt 12 and the tread 4, such that the band 14 covers the belt 12. An outer end P1 of an inner layer 28 layered over a carcass 10 and the outer end Pp of the turn-up portion 24b are positioned facing each other.
