Key statement: Provided is a rubber composition which is improved in rolling resistance and abrasion resistance at the same time without reducing 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.sub.2]SA and a cetyltrimethylammonium bromide adsorption specific surface area CTAB, [N.sub.2]SA/ CTAB, of 1.2 to 1.5 and a nitrogen adsorption specific surface area [N.sub.2]SA of 160 to 300 [m.sup.2]/g.
