PROBLEM TO BE SOLVED: To provide a rubber composition for a sidewall having satisfactory workability and excellent rubber strength and to provide a tire having the sidewall manufactured by using the composition. SOLUTION: The rubber composition for the sidewall includes a diene rubber and a hydrogenated liquid polybutadiene. The hydrogenated liquid polybutadiene content is 1 to 15 pts.mass based on 100 pts.mass diene rubber. The hydrogenated liquid polybutadiene has a number average molecular weight of 600 to 20,000 and 20 to 60 mol% hydrogenation rate of double bonds. COPYRIGHT: (C)2010,JPO&INPIT |
