Plasticizing system which can be used in particular for plasticizing a diene elastomer composition for tyres, the said plasticizing system comprising, in combination: a plasticizing hydrocarbon resin, the glass transition temperature of which is greater than 0° C.; and a phthalate diester corresponding to the formula (I): in which the R radicals, which are identical or different, represent a hydrocarbon radical. The invention also relates to a rubber composition incorporating the said plasticizing system and also to the use of such a composition in the manufacture of a tyre or of a semi-finished rubber product for tyres, in particular of a tyre tread; such a tread exhibits an improved wet grip without penalizing its wear resistance.
