PURPOSE: A rubber composition for tire having improved abrasion resistance is provided which uses a carbon black having a colloidal characteristic in the specific range and has good low exothermicity, chip-cut resistance and abrasion resistance. CONSTITUTION: A rubber composition improved abrasion resistance is composed of a carbon black, which is 130-150 m¬2/g of CTAB, 120-145 mg/g of ISA, 120-140 ml/100g of DBP, 100 ml/100g of C-DBP, more than 110 of TINT, 110-150 m¬2 of N2SA, 110-135 m¬2/g of STST, less than 50% of toluene decolorization(@ 342 nm), 1.0-1.3 of N2SA/STSA, 0-35 of N2SA-STSA, and an ordinary additive. |
