The present invention relates to a tire tread rubber composition for a high speed racing car and, more specifically, to a tire tread rubber composition which comprises 130 to 160 parts by weight of a master batch including rubber, carbon black, and process oil; 60 to 70 parts by weight of raw material rubber; 40 to 60 parts by weight of the carbon black; and 10 to 40 parts by weight of the process oil, and can improve cornering performance and road surface grip force when running at high speed, and to a tire produced by using the same. The tire tread rubber composition of the present invention has no tread performance deviation and can control only heat performance while maintaining hardness and material properties. |
