A method is disclosed for producing a tire rubber composition containing silica, a crosslinking compounding ingredient, and a rubber component containing 70 mass% to 100 mass% of a hydrogenated copolymer. The method includes hydrogenating an aromatic vinyl-conjugated diene copolymer, having a weight average molecular weight of 300,000 or more as measured by gel permeation chromatography, and having a hydrogenation rate of a conjugated diene moiety of 80 mol% or more. The method incudes: a first step of mixing 50 mass% to 95 mass% of 100 mass% of the hydrogenated copolymer with a total amount of the silica; a second step of mixing a rest of the hydrogenated copolymer with a mixture obtained in the first step; and a third step of mixing the crosslinking compounding ingredient with a mixture obtained in the second step.
