Provided is a tire rubber composition enabling a well-balanced improvement in rolling resistance, wear resistance, and wet skid performance. The invention pertains to a tire rubber composition in which a specific silica is blended into a rubber blend comprising a modified diene-based rubber (A) modified with a specific acrylamide compound and a modified diene-based rubber (B) modified with either a specific silicon or tin compound and a specific modifying compound, or with the modifying compound, the weight-average molecular weight of the rubbers (A) and (B) overall being 300,000-1,400,000. |
