Beschreibung
Zusammenfassung:	Disclosed are a rubber composition for tire tread and a tire manufactured using the same, in which the rubber composition for tire tread comprises a raw material rubber, which comprises a first solution-polymerized styrene-butadiene rubber with a low glass transition temperature (Tg) and a second solution-polymerized styrene-butadiene rubber with a high glass transition temperature (Tg), a reinforcing filler, a silane coupling agent, a functionalized liquid polymer, and a first resin with a high glass transition temperature and a second resin with a low glass transition temperature.The rubber composition for tire tread maximizes the dispersion of silica and the interaction with rubber, and thus, the rubber composition is excellent in all of the properties with respect to wear resistance, low fuel economy, and braking performance.
