The present invention relates to a tread rubber composition maintaining low rolling resistance by fine particles of carbon black dispersed in rubber, while improving abrasion resistance by increasing adhesion to rubber by including the carbon black having uniform particles as an enhancer. Provided is a tire tread rubber composition which is characterized by including 40-80 parts by weight of carbon black having width of a particle distribution chart of 10 to 20 nm and having ratio of half width of a particle diameter distribution chart and mode of particle size of 0.7 or less with respect to 100 parts by weight of raw rubber.
본 발명은 입자가 균일한 카본블랙을 보강제로 포함함으로써, 카본블랙의 미세 입자가 고무내에 분산되어 저회전 저항 특성을 유지하면서, 고무와의 결합력을 향상시켜 내마모성을 향상시킨 트레드 고무 조성물에 관한 것으로서, 원료고무 100 중량부에 대하여, 입자 분포도의 폭이 10∼20nm이고, 입자경 분포도의 반치폭(half width)과 입자 크기의 최빈값(mode)의 비가 0.7 이하인 카본블랙 40~80 중량부를 포함하는 것을 특징으로 하는 타이어 트레드 고무 조성물을 제공한다.
