Abstract
A plasticizing system used for plasticizing a diene rubber composition is based on an MES or TDAE oil and on C5 fraction/vinylaromatic copolymer resin, in particular a copolymer of a C5 fraction and of styrene resin. A rubber composition exhibiting an improved abrasion and cut resistance is based on at least a diene elastomer, a reinforcing filler, a crosslinking system, and a plasticizing system comprising between 5 and 35 phr of an MES or TDAE oil and between 5 and 35 phr of such a resin. A tire is formed of the above mentioned rubber composition. A process for preparing such a composition, use of said composition for the manufacture of a finished article or of a semi-finished product intended for a motor vehicle ground-contact system, in particular a tire and a tread of such a tire.
