RUBBER COMPOSITION AND TIRE USING THE SAME

Provide are a rubber composition for tire which is excellent in a wet grip performance and abrasion resistance and which has small rolling resistance and a low fuel consumption, and a tire prepared by using the above rubber composition. The rubber composition is prepared by compounding 100 parts by mass of a rubber component comprising a styrene-butadiene rubber or a styrene-butadiene rubber and a butadiene rubber with 2 to 200 parts by mass of carbon black as a reinforcing filler, wherein the carbon black has at least a hydrogen release rate of 0.2 % by mass or more and/or a ratio NSA/CTAB of 1.2 to 1.5 in which NSA is a nitrogen adsorption specific surface area and CTAB is a cetyltrimethylammonium bromide adsorption specific surface area, and has a NSA of 160 to 300 m/g.
