The present invention relates to a rubber composition for tread which is capable of improving wear resistance and tear resistance and reducing rolling resistance in a compatible manner. Specifically, the present invention relates to a rubber composition for tread, produced by blending carbon black with rubber components including modified conjugated diene-based polymer having at least one nitrogen-containing functional group, wherein the carbon black is obtained by a specific process and light transmittance of toluene extract thereof observed at the multi-stage rapid cooling medium introduction means satisfies relationships of formula (I) and formula (II) below. 10<X<40  (I) 90<Z<100  (II) In the formulae, X represents light transmittance of toluene extract (%) of carbon black after the first rapid cooling medium, counted from the raw material introduction position, is introduced, and Z represents light transmittance of toluene extract (%) of carbon black after the last rapid cooling medium, counted from the raw material introduction position, is introduced. |
