Abstract
A cross-linkable or cross-linked rubber composition usable to constitute a tire tread having improved wear resistance, to such a tread and to a tire incorporating this tread. The composition is particularly applicable to tires of passenger-vehicle type. The rubber composition includes a plasticizing resin of number-average molecular weight of from 400 to 2000 g/mol, the resin having units resulting from the polymerization of a monocyclic or bicyclic unsaturated terpene, in a mass fraction of from 70% to 100%, and having a glass transition temperature greater than 50° C. and less than 120° C.
