摘要： PROBLEM TO BE SOLVED: To provide a rubber composition for tire and tire excellent in rolling resistance, braking performance in wet condition, handling in wet and dry condition, etc.
SOLUTION: The invention relates to the rubber composition comprised of a functionalized styrene/butadiene elastomer containing internal silanol and/or siloxy group(s) therein with pendent silanol and/or alkoxy groups of a polymodal (e.g. bimodal) molecular weight distribution, a dispersion therein of a synthetic amorphous silica and styrene/alpha-methylstyrene resin, and the invention relates to the tire using the same. In one aspect, said rubber composition may contain at least one additional diene-based elastomer. In another aspect, at least a portion of said synthetic amorphous silica may be in a form of pre-treated precipitated silica aggregates which have been pre-treated to reduce hydroxy groups on their surface prior to blending with said functionalized styrene/butadiene elastomer.
