Specifically, the present invention provides a rubber composition comprising a rubber composition and hydrated silica, wherein "CTAB" ([m.sup.2]/g) as specific surface area by cetyltrimethylammonium bromide adsorption and "IB" as ink bottle-shaped micropore index, of the hydrated silica, satisfy a specific relationship and "weight loss on ignition" (mass %) as weight loss when the hydrate silicate is heated at 750[degrees]C for three hours and "weight loss on heating" (mass %) as weight loss when the hydrate silicate is heated at 105[degrees]C for two hours satisfy a specific relationship.
