Zusammenfassung:	There is provided a rubber composition capable of producing a tire which improves rolling resistance performance, wet skid performance and drivability of a vehicle in good balance, and a tire having a tread comprising thereof. A rubber composition comprising 30 to 150 parts by weight of the total of (1) silica with a nitrogen adsorption specific area of 100 m 2 /g or less and (2) silica with a nitrogen adsorption specific area of 180 m 2 /g or more based on 100 parts by weight of a rubber component, wherein the content of silica (1) and silica (2) satisfies the following formula, and a tire having a tread comprising thereof: [ Content€ƒof€ƒsilica€ƒ ( 1 ) ] × 0.2 ‰¤ [ content€ƒof€ƒsilica€ƒ ( 2 ) ] ‰¤ [ content€ƒof€ƒsilica€ƒ ( 1 ) ] × 6.5.
