The present invention relates to a rubber composition for tire tread having improved braking performance on a wet road while maintaining wear resistance and low fuel consumption performance, and a tire manufactured by using the same. The rubber composition for tire tread according to the present invention includes raw material rubber containing solution-polymerized styrene-butadiene rubber whose terminal or both terminals are modified with amino silane and/or amine, silica, a resin, and PVA which is a water-soluble polymer, and a tire is manufactured with the composition. According to the present invention, by combining solution-polymerized styrene butadiene rubber (SSBR) of various glass transition temperatures (Tg) with a high functionalization rate and applying PVA (polyvinylachohol), which is a resin and water soluble polymer, braking performance in a wet road can be improved while maintaining tire wear resistance and low fuel consumption performance.

    본 발명은 내마모성, 저연비 성능을 유지하면서 젖은 노면 제동 성능을 향상시킨 타이어 트레드용 고무 조성물 및 이를 이용하여 제조한 타이어에 관한 것이다. 본 발명에 다른 타이어 트레드용 고무 조성물은 amino silane 및/또는 amine계로 말단 또는 양말단이 변성된 용액 중합 스티렌-부타디엔 고무를 포함하는 원료고무, 실리카, 수지, 수용성 고분자인 PVA를 포함하며, 상기 조성으로 타이어가 제조된다. 본 발명에 의하면 관능화율이 높은 다양한 유리 전이 온도(Tg)의 용액 중합 스티렌 부타디엔 고무(SSBR)을 조합하고, Resin 및 Water Soluble Polymer인 PVA (Polyvinylachohol)을 적용함으로써 타이어의 내마모성, 저연비 성능을 유지하면서 젖은 노면 제동 성능을 향상시킬 수 있다.
