摘要：
A rubber composition is based on at least 80 phr (parts by weight per hundred parts by weight of elastomer) of a styrene/butadiene elastomer (SBR) referred to as low-Tg SBR, the glass transition temperature (Tg) of which is less than −60° C.; at least 130 phr of reinforcing filler; at least 110 phr in total of a plasticizing system comprising a hydrocarbon-based resin at a content within a range extending from 70 to 100 phr and a plasticizing oil at a content within a range extending from 10 to 40 phr; and a vulcanization system.
