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. 本发明涉及一种轮胎胎面用橡胶组合物以及利用上述橡胶组合物制造的轮胎，上述轮胎胎面用橡胶组合物，包含：含有玻璃化转变温度(Tg)较低的第1溶聚丁苯橡胶以及玻璃化转变温度(Tg)较高的第2溶聚丁苯橡胶的原料橡胶；补强性填充材料；硅烷偶联剂；功能化的液态聚合物(Liquid Polymer)；玻璃化转变温度较高的第1树脂；以及，玻璃化转变温度较低的第2树脂。上述轮胎胎
