PROBLEM TO BE SOLVED: To provide a tire composition for a motorcycle, which can reduce fuel consumption while reducing rolling resistance, and is excellent in rigidity feeling during turn, and a tire for the motorcycle.SOLUTION: In a tire composition for a motorcycle, a value of loss tangent tanδ at 60°C in measurement temperature is 0.182 or less, a value to be determined by the following expression (1) from the value of the loss tangent tanδ at -30°C in measurement temperature and the value of dynamic complex modulus E* of elasticity at -30°C, is 1.4[MPa] or more, a value of dynamic complex modulus E* of elasticity at 30°C in measurement temperature is 9.6[MPa] or more, and the value of dynamic complex modulus E* of elasticity at 60°C in measurement temperature is 6.9[MPa] or more: a physical index =104×tanδ/E* (1). |
