<p>The invention relates to a crosslinkable or crosslinked rubber composition which can be used to produce a tyre casing tread, one such tread having, in particular, improved wear resistance and a tyre casing having improved durability owing to the incorporation of said tread. The inventive composition is made from one or more diene elastomers and comprises at least one hydrocarbon plasticising resin which is miscible with the diene elastomer(s), said resin having a vitreous transition temperature Tg of between 10 C and 150 C and a molecular mass of between 400 and 2000 g/mol.Said composition comprises (pce: parts by weight per 100 parts of elastomer(s)): said hydrocarbon plasticising resin, having a quantity varying between 5 pce and 35 pce; one or more diene elastomers, having a quantity that is greater than 50 pce and up to 100 pce, each having a Tg of between -65 C and -10 C; and one or more diene elastomers, having a quantity that is less than 50 pce and up to 0 pce, each having a Tg of between -110 C and -80 C.</p> |
