<p>A rubber composition, comprising a rubber component, and a carbon black, the carbon black satisfying the dibutyl phthalate (DBP) absorption number [unit:mL/100g] of the carbon black is from 90 to 180, the difference of the BET specific surface area (BETS)[unit: m 2 /g] of the carbon black from the external specific surface area (STSA) [unit: m 2 /g] thereof satisfies the following: 5 < (BET5) - (STSA) < 12, the ratio between the Stokes diameter (Dst) of the carbon black and the Stokes diameter distribution (”D - 50 (half band width)) thereof satisfies the following: 0.70 < the ratio of (”D - 50)/(Dst) < 1.10, and the ratio between the BET specific surface area (BET5) [unit: m 2 /g] of the carbon black and the iodine adsorption number (IA) [unit: mg/g] thereof satisfies the following: 1.05 < the ratio of (BET5)/(IA) < 1.35.</p> |
