A rubber composition comprising (A) 100 parts by weight of a raw material rubber which contains not less than 30 % by weight of at least one partially hydrogenated rubber of a conjugated diene rubber, wherein 5 to 70 % of the unsaturated double bonds of the conjugated diene portion thereof have been hydrogenated; (B) 10 to 150 parts by weight of a silica; (C) 0.1 to 20 parts by weight of an organo-silane coupling agent; and (D) 0.1 to 10 parts by weight of a vulcanizing agent. The rubber composition of the present invention has extremely excellent resilience, low exothermic property, and excellent wet skid resistance, and further improved processability, and therefore, by utilizing the characteristics, can be used to make industrial parts such as tires for various types of automobiles, rubber vibration insulators, belts, and the like. Especially when it is used for a tire, it can be suitably used for a tread portion, a cap tread portion, and an undertread portion of a tire, for instance, and exhibits the effect of saving fuel cost by improving fuel efficiency of a vehicle which utilizes the tire. |
