RUBBER COMPOSITION FOR TIRE TREAD

A rubber composition for a tire tread including 100 parts by weight of a diene-based rubber and 5 to 150 parts by weight of carbon black having a nitrogen adsorption specific area NSA (m/g) of 80 to 150 and satisfying a relationship between a TINT (%) and dibutyl phthalate absorption DBPA (ml/100 g) of TINT (%) > 1.4 DBPA (ml/100 g) and capable of increasing the frictional force without impairing the hysteresis loss.
