PURPOSE: Tire tread rubber composition which can solve the processing problem such as adhesion of tire tread composition onto the Banbary machine or open roll without decreasing the grip ability and traction ability is provided CONSTITUTION: Tire tread rubber composition for high speed racing car comprises 100 parts by weight of styrene-butadiene rubber containing 35-45 % of styrene bond, 100 to 140 parts by weight of carbon black having nitrogen absorbing surface = 120 to 160 m¬2/g and DPB oil absorbing rate = 120cc/100g, aromatic process oil, 80 to 120 parts by weight of mixture of fatty acid ester and 2 to 8 parts by weight of metal salt (specific gravity: 1.07-1.17, softening point: 60-80C), and conventional additives. Using this composition, problem of adhesion onto Banbary machine or open roll can be solved without decreasing traction ability and grip ability.
