PURPOSE: A rubber composition provides the tire thread to improve abrasion-proof, having a low exothermicity and a low mileage, by using butadiene rubber to be made by the solution polymerization and using a specific carbon black as a useful reinforce for controlling the composition of butadiene Tg (glass transition temperature) and a fine structure. CONSTITUTION: The rubber composition for tire thread consists of the material rubbers 100 weight % containing of raw rubbers, i.e., diene-series rubber 100 % and butadiene rubbers 30 weight % or below; carbon blacks 30 to 100 PHR; and usual additives. |
