    Abstract: 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
