PROBLEM TO BE SOLVED: To provide a pneumatic tire for a two-wheeled vehicle achieving both operation stability on a wet road surface and drain performance at high speed. SOLUTION: Two circumferential main grooves 40 are formed to extend in the circumferential directions on both sides of a tire equatorial plane CL of a tread 28, and a plurality of inclination grooves 42 are formed toward tread ends on the outer side. The inclination grooves 42 are formed narrower on the tread end side and wider on the tire equatorial plane side in such a way that the groove width is gradually increased toward the tire equatorial plane. For a shoulder side range used at the time of cornering, the groove width of the inclination grooves 42 is narrower compared to that on the tire equatorial plane side. An area of a thin land 32 is thus set large to enlarge a contact area with a road surface, so that the operation stability on a wet road surface is improved. A plurality of the circumferential main grooves 40 and the wider parts of the inclination grooves 42 improve drain effects at high speed traveling, so that the generation of a hydroplaning phenomenon can be prevented.
