<p>A rubber composition including 100 parts by weight of natural rubber and/or diene synthetic rubber and 30 - 100 parts by weight of carbon black having the following characteristics: (1) 24M4DBP of 0.95 - 1.30 ml/g; (2) Dst of 50 - 80 nm; (3) DELTA D50/Dst of 0.55 - 0.75; (4) DELTA D10/Dst of 1.0 - 1.5; (5) a component ratio of 20% or less; and (6) CTAB of 120 - 180 m<2>/g. The rubber composition is excellent in abrasion resistance without impairing the low heat generation property and the processability thereof.</p> |
