<p>The present invention relates to a tyre, the tread of which comprises a rubber composition comprising at least: as first elastomer, a diene elastomer; as second elastomer, a thermoplastic polyurethane block copolymer with polyurethane blocks and polydiene blocks; 70 to 150 pce of an inorganic reinforcing filler; a plasticizing system comprising: with a content A of 5 to 60 pce, a hydrocarbon resin, the Tg of which is higher than 20ºC; with a content B of 5 to 60 pce, a plasticizer which is liquid at 20ºC, and the Tg of which is lower than -20ºC; it being understood that A+B is higher than 30 pce. The use of a thermoplastic polyurethane block copolymer with polyurethane blocks and polydiene blocks, in particular in the presence of high filler and plasticizer contents, in the composition of a tyre tread as per the present invention enables tyres having improved grip on wet ground to be obtained.</p> |
