Provided are a rubber composition for tire tread and a tire produced using this rubber composition. The rubber composition for tire tread includes 100 parts by weight of a raw material rubber, 10 to 30 parts by weight of carbon black, and 10 to 80 parts by weight of a master batch including a synthetic rubber that contains a high cis-1,4-polybutadiene rubber matrix and syndiotactic 1,2-polybutadiene dispersed in the rubber matrix. The rubber composition for tire tread can enhance the cut-chip performance and the initial grip performance of a tire produced therefrom.
