PURPOSE: A tire carcass rubber composition is provided to improve vulcanization stability and curing rate of a rubber composition and tensile properties before and after aging by employing N,N-bis-(2-hydroxyethyl)aniline as a vulcanization accelerator. CONSTITUTION: A tire carcass rubber composition comprises a base rubber 100.0 parts by weight, filler 40~60 parts by weight and N,N-bis-(2-hydroxyethyl)aniline 1.0~3.0 parts by weight represented by formula(1) as a vulcanization accelerator. The filler is at least one selected from the group consisting of carbon black, syndiotactic-1,2-polybutadiene, silica, titanium dioxide, clay, layered silicate, tungsten, talc, mica, calcium carbonate, talc, vermiculate, and hydrotalcite. |
