PROBLEM TO BE SOLVED: To produce tires excellent in processing characteristics, weather resistance, ozone resistance, fatigue resistance, low heat generation, etc., without substantially impairing the damping property inherent in a conjugated diene rubber. To provide a suitable rubber composition. SOLUTION: (A) an ethylene copolymer rubber comprising an ethylene unit, an α-olefin unit and a non-conjugated polyene unit having a specific structure, (B) a conjugated diene rubber, and in some cases, (C) a halogenated butyl rubber, and (D) A rubber composition containing a white filler is provided. |
