PROBLEM TO BE SOLVED: To provide a rubber composition which improves abrasion resistance, simultaneously realizes low rolling resistance, and is desirable for tires. SOLUTION: This rubber composition comprising a dienic rubber and a reinforcing agent is characterized by using silica and carbon black as the reinforcing agent, using the carbon black in an amount of 60 to 95 wt. % based on the total amount of the reinforcing agent, and adding a triblock copolymer comprising the block segment of styrene monomer units and the block segment of rubber monomer units in an amount of 5 to 35 pts. wt. per 100 pts. wt. of the dienic rubber.
