Abstract

PURPOSE: The titled composition having improved abrasion resistance, low-rolling resistance and improved wet grip, prepared by adding a specified styrene/butadiene copolymer rubber to a synthetic diene rubber-containing tread composition for passenger car tires.
CONSTITUTION: A composition, a vulcanizate of which has resilience at 23°C ≥ 55%, obtained by adding 30W70wt% styreney butadiene copolymer rubber, styrene content 5W18wt%, 1,2-addition content of butadiene 50W80wt%, and, if necessary, carbon black, iodine adsorption 65W90mg/g, dibutyl phthalate adsorption 140W170ml/100g, to a tread rubber composition containing at least one synthetic diene rubber, for passenger car tires.
