The present invention provides a rubber composition for a tire, the rubber composition containing: a diene rubber; silica; and a heterocyclic compound (where, the heterocyclic compound does not have a silicon atom) having a hydrocarbon group having from 3 to 30 carbons and at least one type of heterocycle selected from the group consisting of a piperazine ring, a morpholine ring, and a thiomorpholine ring; an average glass transition temperature of the diene rubber being −50° C. or higher; a content of the silica being from 80 to 200 parts by mass per 100 parts by mass of the diene rubber; and a content of the heterocyclic compound being from 0.5 to 20% by mass with respect to the content of the silica. Such rubber composition has excellent processability, exhibits excellent wet grip performance and has low rolling resistance when the rubber composition is formed into a tire.
