Problem: To provide a rubber composition for use in tire treads that enhances low rolling resistance and wet performance to conventional levels or above while maintaining and enhancing extrudability. Solution: A rubber composition for use in tire treads comprising from 60 to 130 parts by weight of silica per 100 parts by weight of diene rubber containing not less than 50% by weight of hydroxyl group-containing modified styrene butadiene rubber, in which the weight ratio of oil to filler containing the silica is not greater than 0.25, and a silane coupling agent having a mercapto group and an Si-O bond is compounded in an amount from 4 to 15% by weight of the silica content, and diethylene glycol is compounded in an amount from 1 to 6% by weight of the silica content.
