Abstract
An object of the present invention is to provide a rubber composition for a tire, capable of achieving both good rolling resistance properties and good wear resistance in a sufficiently compatible manner when the rubber composition is applied to a component member of a tire. Specifically, the present invention provides a rubber composition comprising a rubber composition and hydrated silica, wherein 'CTAB' (m/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” as weight loss when the hydrate silicate is heated at 750° C. for 3 hours and “weight loss on heating” as weight loss when the hydrate silicate is heated at 105° C. for 2 hours satisfy a specific relationship.
