The present invention relates to a rubber composition for a tire tread, which comprises, on the basis of 100 parts by weight of raw material rubber, 10 to 30 parts by weight of styrene oil containing styrene and butadiene in a weight ratio of 85:15 to 95:5, and 35 to 40 parts by weight of process oil, and according to the present invention, the wet grip performance can be improved while the amount of the process oil used is not increased, so that the driving stability can be increased by improving the friction force between tires and the road surface.
본 발명은 원료고무 100 중량부에 대하여, 스티렌과 부타디엔을 85:15~95:5의 중량비로 함유하는 스티렌 오일(styrenic oil) 10~30 중량부 및 공정 오일 35~40 중량를 포함하는 타이어 트레드용 고무 조성물에 관한 것으로, 공정 오일의 사용량을 높이지 않는 동시에, 웨트 그립 성능을 향상시킬 수 있기 때문에, 타이어와 노면의 마찰력을 향상시켜 주행 안정성을 높일 수 있는 장점이 있다.
