The present invention relates to a heavy duty tire rubber composition having excellent wettability and rolling resistance characteristics. The heavy duty tire rubber composition having excellent wettability and rolling resistance characteristics, according to the present invention, comprises: 3 to 20 parts by weight of a sol-gel transition polymer per 100 parts by weight of raw rubber. The sol-gel transition polymer exhibits a sol-gel transition as the temperature increases. Accordingly, as the temperature increases, the sol-gel transition characteristics are utilized to exhibit excellent effects in both wet road characteristics and rolling resistance characteristics, which are trade-off in nature.

    본 발명은 젖음성과 회전저항특성이 우수한 중하중용 타이어 고무 조성물을 개시한다. 본 발명에 따르는 젖음성과 회전저항특성이 우수한 중하중용 타이어 고무 조성물은 원료고무 100 중량부에 대하여 졸겔전이고분자 3 내지 20 중량부를 포함하고, 상기 졸겔전이고분자는 온도가 증가함에 따라 졸-젤 전이를 보이는 것을 특징으로 하는데 이에 의하면, 온도가 증가함에 따라 졸-젤 전이 특성을 이용하여 트레이드-오프 관계인 젖은 노면 특성과 회전 저항 특성이 모두 우수한 효과를 발휘한다.
