Abstract

본 발명은 승용차용 타이어 트레드 고무조성물에 관한 것으로서, 보다 상세하게는 표면화학특성(surface activity)이 우수하고 입자경이 클 뿐 아니라 응집체 크기 및 분포(Aggregate size and distribution)가 각각 크고 넓은 카본블랙을 사용함으로써, 타이어의 회전저항을 개선시킨 타이어 트레드 고무조성물에 관한 것이다.The present invention relates to a tire tread rubber composition for a passenger car, and more particularly, a carbon black having excellent surface activity and a large particle diameter as well as a large aggregate size and distribution are used. The present invention relates to a tire tread rubber composition having improved tire rolling resistance.
