Abstract: Proposed is a rubber composition for a tire tread, which includes: a solution-polymerized elastomer having a conjugated diene-based monomer unit, a solution-polymerized elastomer having an aromatic vinyl monomer unit and a conjugated diene-based monomer unit, or a combination thereof, at 100 parts by weight; and a plasticizer containing an aromatic petroleum resin and an aliphatic olefin polymer, at 10 to 50 parts by weight. Further, a manufacturing method of the rubber composition for a tire tread is proposed.
