A rubber composition for a tire tread groove of the present invention includes 50 to 90 parts by weight of diene-based natural rubber, 10 to 50 parts by weight of butadiene rubber, 10 to 60 parts by weight of carbon black, 1 to 6 parts by weight of an amine-based anti-aging agent, and an additive. According to the present invention, by inserting, at a groove position of a tire tread portion, the rubber composition having high crack resistance, ozone resistance and heat resistance and having low hysteresis, the occurrence of fatigue breakdown due to deformation of a tire or a tread block during driving, that is, groove crack can be prevented.

    본 발명의 타이어 트레드 그루브용 고무 조성물은, 디엔계 천연고무 50~90 중량부, 부타디엔 고무 10~50 중량부, 카본블랙 10~60 중량부, 아민계 노화방지제 1~6 중량부 및 첨가제를 포함한다. 본 발명에 의하면, 타이어 트레드부의 그루브 위치에 내크랙성, 내오존성, 내열성이 강하며, 히스테리시스가 낮은 고무 조성물을 삽입함으로써, 주행시 타이어의 변형 또는 트레드 블록의 변형에 따른 피로 파괴, 즉 그루브 크랙의 발생을 방지할 수 있다.
