PROBLEM TO BE SOLVED: To overcome difficulty to satisfy various properties of high durability and abrasion resistance of a wet tire for competition without reducing wet grip performance.SOLUTION: The above described problem is solved by a rubber composition for tire by blending 100 pts.mass of a diene rubber containing an aromatic vinyl-conjugated diene rubber having Tg of -35°C or more and weight average molecular weight of 800,000 to 2,000,000, 120 pts.mass or more of silica, a specific silane coupling agent of 2 to 20 mass% based on the silica, a low molecular weight aromatic vinyl-conjugated diene rubber of 5 to 100 pts.mass and a styrenated phenol compound mainly containing distyrenated phenol or tristyrenated phenol of 0.5 to 20 pts.mass.SELECTED DRAWING: None |
