PURPOSE:To improve performance such as anti-wet-skid performance by using vulcanizable rubber composition in a tread, in which two kinds or more diene series rubber with specific composition, specific carbon black, and nitroso-compound with a specific structural formula are blended as specific ratios. CONSTITUTION:A tread is configured with vulcanizable rubber composition in which 30 to 80pts.wt. of carbon black with iodine adsorption amount of exceeding 70mg/g and dibutyl phthalate oil absorption amount of exceeding 90ml/100g and 0.2 to 10pts.wt. of nitroso-compound selected from the nitroso quinoline or nitroso aniline compound shown in formulas I and II are blended in 100pts.wt. of rubber component made of 100 to 25pts.wt. of one or more diene series rubber consisting of stylene content of 0-30% and the vinyl coupling 25-95% of the butadiene section and 0-75pts.wt. of one or more diene series rubber different from the former. As a result, anti-wet-skid performance, rolling resistance, resistance to wear, and running on the snow and ice can be improved. |
