Abstract: In the present invention, in order to provide a rubber composition for a tire that can improve dry grip performance, enhance strength at break, exhibit excellent wear resistance, and suppress temperature dependency of hardness, from 50 to 200 parts by mass of carbon black having a nitrogen adsorption specific surface area (N2SA) from 100 to 500 m2/g and from 5 to 50 parts by mass of a terpene phenol resin having an acid value of 30 mgKOH/g or greater and a hydroxyl value of 5 mgKOH/g or greater are blended, per 100 parts by mass of a diene rubber containing a styrene-butadiene copolymer rubber.

Abstract: Provided is a rubber composition for tires containing, per 100 parts by mass of diene rubber, from 5 to 120 parts by mass of carbon black having a nitrogen adsorption specific surface area N2SA of 90 m2/g or less and a compressed DBP absorption (24M4) of 95 to 120 mL/100 g, a ratio ?Dst/Dst of a half width ?Dst (nm) of a mode diameter Dst to the mode diameter Dst (nm) in a Stokes diameter mass distribution curve of aggregates of the carbon black being 0.65 or greater, and the N2SA, (24M4), and Dst satisfying the following formula: (24M4)/Dst<0.0093×N2SA?0.06.
