摘要： To provide a rubber composition for tire treads that enhances processability, wet performance, and wear resistance beyond conventional levels. The rubber composition contains: a diene rubber; from 1 to 25 parts by weight of an aromatic modified terpene resin; from 80 to 150 parts by weight of a silica; from 5 to 50 parts by weight of a carbon black; an oil component, per 100 parts by weight of the diene rubber; and from 0.1 to 20 wt.% of the weight of the silica of an alkyltriethoxysilane having an alkyl group having from 3 to 20 carbons, the diene rubber containing from 10 to 30 wt.% of a natural rubber, from 10 to 30 wt.% of a solution polymerized styrene butadiene rubber having a styrene unit content of 30 to 40 wt.% and from 80 to 40 wt.% of an emulsion polymerized styrene butadiene rubber, and a ratio of a total amount W oil of an oil-extending component contained in the solution polymerized styrene butadiene rubber and/or the emulsion polymerized styrene butadiene rubber, the aromatic modified terpene resin, and the oil component to a weight W NR of the natural rubber (W oil /W NR ) being from 3.0 to 4.0.
