摘要： An object of the present invention is to provide: a rubber composition which, when it is applied to a component member (such as a tread) of a tire, exhibits good wear resistance without deteriorating rolling resistance of the tire; a cross-linked rubber composition obtained by cross-linking the rubber composition; and a tire using the rubber composition or the cross-linked rubber composition as a material thereof. Specifically, the present invention provides a rubber composition obtained by blending and kneading a rubber component and hydrated silica together, characterized in that: provided that D represents the average primary particle diameter and LP represents the log differential pore volume at a pore diameter of 30 nm, of the hydrated silica in the rubber composition, D and LP satisfy relationships represented by following formula (1) and (2). LP>−0.045×D+1.45 (1) D
摘要翻译：本发明的目的在于提供一种橡胶组合物，其在施加到轮胎的构成部件（胎面）时表现出良好的耐磨性，而不会降低轮胎的滚动阻力; 通过交联橡胶组合物得到的交联橡胶组合物; 以及使用橡胶组合物或交联橡胶组合物作为其材料的轮胎。具体地说，本发明提供了通过将橡胶成分和水合二氧化硅共混并捏合而得到的橡胶组合物，其特征在于：D表示平均一次粒径，LP表示孔径为30nm的对数微分孔体积的橡胶组合物中的水合二氧化硅，D和LP满足由下式（1）和（2）表示的关系。 LP> -0.045×D + 1.45（1）D <30nm（2）。
