PURPOSE: A tire tread rubber composition provides a tire with improved abrasion resistance and improves tire replacement period due to abrasion. CONSTITUTION: A tire tread rubber composition includes 1-10 parts by weight of a fatty acid amide represented by chemical formula 1: C_nH_(2n+1)CONHCH_2OH based on 100.0 parts by weight of raw rubber. In chemical formula 1, n is 6-18. The raw rubber is a mixed rubber formed of 5-95 parts by weight of a butadiene rubber and 5-95 parts by weight of natural rubber. The butadiene rubber is selected from a butadiene rubber manufactured by using a lithium catalyst, a butadiene rubber manufactured by using a neodymium catalyst, a butadiene rubber manufactured by using a lithium catalyst, or a butadiene rubber manufactured by using a neodymium catalyst. |
