ABSTRACT:
A rubber composition for a pneumatic tire containing 100 parts by weight of a diene-based rubber and 5 to 120 parts by weight of carbon black having a particle size of 15 to 40 nm, a nitrogen absorption specific surface area N2SA of 60 to 200 m2/g, and a pH of 1 to 5 or 8.5 to 13, which can improve wet performance of a tire without causing problems in productivity and conductivity.
