PURPOSE: A tire rubber composition for a tire cacas is provided to improve the scorch resistance without using a separate scorch retarder by applying a thiabicyclo nonane system compound. CONSTITUTION: A tire rubber composition for a tire cacas contains 1.5~2 parts of sulfenamide system compound by weight as a first vulcanization accelerator, and 1.5~2 parts of thiabicyclo nonane system compound by weight as a second vulcanization accelerator, for 100 parts of raw rubber by weight. The sulfenamide system compound is either N-cyclohexylbezothiazole-2-sulfenamide or N-oxyethylbenzothiazole-2-sulfenamide. |
