About the difficulty for being kneaded rubber and a large amount of silica dioxide granules, the present invention solves the problems, such as follows：A kind of rubber composition for tire is provided, the dispersibility of wherein silica can be improved, and can increase the grain size of silica simultaneously and be compounded a large amount of silica dioxide granules.The present invention is a kind of rubber composition for tire, and the composition includes natural rubber and/or diene series rubber component, fatty acid glyceride composition and silica containing glycerol fatty acid monoester.The BET specific surface area of the silica is 100 130m 2 / g hereinafter, and the rubber components based on 100 mass parts, the rubber composition for tire contain the silica of 80 mass parts or more.The tire manufactured using above-mentioned rubber composition for tire can allow to take into account wet Pavement Performance, grip performance and abrasion performance, and allow to ensure the processing performance in manufacture due to reducing viscosity. |
