The present invention aims to provide a sidewall rubber composition that has excellent low rolling resistance characteristics and can improve pass-by noise, when applied to a tire. In order to achieve this aim, this sidewall rubber composition used in tire sidewalls is characterized by having a tan delta ratio at 0 degC relative to a tan delta ratio at 30 degC (0 degC tan delta/ 30 degC tan delta) of at least 2.00.
本发明旨在于提供侧壁用橡胶组合物,当应用于轮胎时其具有优异的低滚动阻力性能并且可以改善通过噪音。为了实现该目的,用于轮胎侧壁部的该侧壁用橡胶组合物的特征在于:在0℃下的tanδ相对于在30℃下的tanδ的比例(0℃tanδ/30℃tanδ)为2.00以上。
