PURPOSE: A tire tread rubber composition is provided to be blended at a high temperature, to improve rotation resistance and properties such as braking power and abrasion. CONSTITUTION: A tire tread rubber composition comprises a base rubber 100.0 parts by weight, a first filler 50~80 parts by weight, a gamma mercapto propyl di-penta-ethoxy tridecaoxy ethoxy silane 3~15 parts by weight as a silane coupling agent, and tetrabenzylthiuram disulfide 0.05~2 parts by weight as a vulcanization accelerator. The first filler is at least one selected from the group consisting of silica, carbon black, calcium carbonate and clay. |
