PROBLEM TO BE SOLVED : To provide a tire improving low fuel consumption performance and wet skid performance in a good balance by improving dispersibility of silica as a reinforceable filler in rubber.SOLUTION : There is provided a rubber composition manufactured by compounding a diene rubber of 100 pts.mass, silica of 20 to 150 pts.mass and an organosilane represented by the following formula 1 and/or 2 of 2 to 20 mass% based on the silica mass. In the formulae (1) and (2), X, Xand Xare H or alkyl groups having 1 to 3 carbon atoms, Aand Aare saturated or unsaturated alkyl groups having 1 to 22 carbon atoms, benzimidazole groups, benzothiazole groups, imidazole groups or -CH-SiRRRand at least one contains silicon, R, Rand Rare alkyl groups or alkoxy groups having 1 to 3 carbon atoms and x=2 to 4. |
