Plasticizing system which can be used in particular for the plasticizing of a tyre diene elastomer composition comprising, in combination: a plasticizing hydrocarbon resin, the glass transition temperature of which is greater than 0° C.; and a tri- or pyromellitate ester corresponding to the formula (I): in which the R radicals, which are identical or different, represent a hydrocarbon radical and the R′ radical represents hydrogen or the COOR group. The invention also relates to a rubber composition incorporating the said plasticizing system and to the use of such a composition for the manufacture of a tyre or tyre semi-finished product made of rubber, in particular of a tyre tread, exhibiting an improved wear resistance without having a detrimental affect on its wet grip.
