PROBLEM TO BE SOLVED: To provide a tire for a motorcycle with excellent grip performance and durability performance at high speed traveling. SOLUTION: A tread 4 of the tire for the motorcycle comprises an under layer 30; a base layer 32; and a cap layer 34. Any of the under layer 30, the base layer 32 and the cap layer 34 comprises cross-linked rubber. A foaming temperature Tb of the base layer 32 is higher than a foaming temperature Tc of the cap layer 34. A foaming temperature Tu of the under layer 30 is higher than the foaming temperature Tb of the base layer 32. Difference of the foaming temperature Tb of the base layer 32 and the foaming temperature Tc of the cap layer 34 is 10°C or higher. Difference of the foaming temperature Tu of the under layer 30 and the foaming temperature Tb of the base layer 32 is 10°C or higher. COPYRIGHT: (C)2006,JPO&NCIPI |
