Provide is a rubber composition which is improved in rolling resistance and abrasion resistance at the same time without reducing a wet grip performance, and the rubber composition is prepared by compounding 100 parts by mass of a rubber component containing 30 % by mass or more of polyisoprene with 2 to 200 parts by mass of carbon black having a hydrogen release rate of 0.2 % by mass or more and/or a ratio of a nitrogen adsorption specific surface area N 2 SA and a cetyltributylammonium adsorption specific surface area CTAB, N 2 SA/CTAB, of 1.2 to 1.5 and a nitrogen adsorption specific surface area N 2 SA of 160 to 300 m 2 /g. |
