Provided is a rubber composition for a tire tread that simultaneously improves wet road braking performance, abrasion resistance, and fuel economy performance. The rubber composition for a tire tread according to the present invention comprises: 100 parts by weight of raw rubber; and 90 to 140 parts by weight of a reinforcing filler, wherein the raw rubber is 25 to 65 parts by weight of gocis neodymium butadiene rubber (Nd-BR), 5 to 45 parts by weight of high functional lithium butadiene rubber (functionalized Li-BR), and 20 to 50 parts by weight of solution polymerization styrene-butadiene rubber. |
