The present invention relates to a tyre, the tread of which includes a rubber composition comprising at least: a diene elastomer; 100 to 150 pce of an inorganic reinforcing filler; a thermoplastic poly(alkylene ester) resin; a plasticising system including: 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 liquid plasticiser at 20ºC, the Tg of which is lower than -20ºC; it being understood that A+B is higher than 40 pce. The use of a poly(alkylene ester) resin, in particular combined with high filler and plasticiser contents, makes it possible to improve the rigidity of the tread and thus the handling of the tyre, without affecting the hysteresis and thus the rolling resistance thereof. |
