PROBLEM TO BE SOLVED: To provide a pneumatic tire for a two-wheeled vehicle improving lateral stiffness at the time of turning, and absorbing performance for absorbing unevenness of a road surface at the time of turning. SOLUTION: The pneumatic tire for a two-wheeled vehicle comprises a carcass, a bead filler having a triangular cross-section and made from rubber, and a hard rubber filler having hardness generally same as the bead filler on a tire width direction outside of a carcass folding portion. An expression 0.6≤W/BW≤1.1 is established, where the tire width direction width of a bottom side portion of the bead filler is W, and a tire width direction width of a bead core is BW. An expression 0.08≤h/SH≤0.20 is established, where a distance from a heel portion end of the bead portion to a tread surface end of a tread portion is SH, and a distance from the heel portion end of the bead portion to a tire diameter direction outside end of the bead filler is h. An expression 0.1≤t/BW≤0.7 is established, where the maximum thickness in a tire width direction of a hard rubber filler is t. COPYRIGHT: (C)2005,JPO&NCIPI
