The present invention is to provide a tire rubber composition by which wet grip performance and low rolling resistance are enhanced equal to or beyond conventional levels while mechanical properties, such as tensile stress, tensile strength at break, and tensile elongation at break, are maintained or enhanced. The tire rubber composition is formed by blending a microparticle composite, which is formed from a solid component of a mixture containing an emulsion of an organic microparticle and a rubber latex, in a sulfur vulcanizable rubber; the emulsion of the organic microparticle being an emulsion containing a microparticle obtained by polymerizing and/or crosslinking at least one selected from the group consisting of polymerizable monomers, and oligomers, prepolymers, and polymers having a reactive functional group and having a molecular weight from 500 to 50000 simultaneously or stepwise in water; and an average particle size of the microparticle being from 0.001 to 100 µm.
