  "textContent": "An object of the present invention is to provide a rubber composition capable of achieving both good rolling resistance properties and good wear resistance in a compatible manner when the rubber composition is applied to a component member, e.g. tread, of a tire. Specifically, the present invention provides a rubber composition comprising a rubber composition and hydrated silica, wherein \"CTAB\" (m 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 °C for 3 hours and \"weight loss on heating\" (mass %) as weight loss when the hydrate silicate is heated at 105 °C for 2 hours satisfy a specific relationship.",
