RUBBER COMPOSITION AND TIRE USING THE SAME

摘要

A rubber composition which comprises 100 parts by weight of a diene based polymer and 20 to 250 parts by weight of a carbon black as a filler, characterized in that the carbon black exhibits a dibutyl phthalate (DBP) absorption of 40 to 180 cm<3>/100 g, a nitrogen absorption specific surface area (N2SA) of 40 to 300 m<2>/ g, a tint (TINT) of 50 to 150 %, a toluene discoloration transmittance of 90 % or more, and the relationship between the nitrogen absorption specific surface area and the toluene discoloration transmittance satisfies the following formula (1): 0.0283 x A x (100 - B) <= 40 (I) wherein A represents a nitrogen absorption specific surface area and B represents a toluene discoloration transmittance. The rubber composition combines high abrasion resistance and low heat buid-up.
