To provide a rubber composition for tire tread, capable of achieving both of low rolling resistance and high abrasion resistance, and to provide the tread and the tire.
The rubber composition for the tire tread, usable for forming the tread of the tire contains a rubber component and ≥30 pts.mass and ≤100 pts.mass of silica based on 100 pts.mass of the rubber component. The rubber component contains ≥5 pts.mass and ≤30 pts.mass of an acrylonitrile-butadiene copolymer rubber obtained by polymerizing acrylonitrile and butadiene based on the whole rubber component. The copolymerized percentage of the acrylonitrile in the acrylonitrile-butadiene copolymer rubber is ≥25 mass%, and the nitrogen adsorption specific surface area of the silica measured by a BET method is ≥50 m
