Abstract:
The present invention relates to a tire, the tread of which comprises an elastomer composition comprising: from 10 to 60 phr of a polybutadiene (BR) elastomer; from 10 to 60 phr of a saturated thermoplastic styrene (TPS) elastomer; a reinforcing filler.The combined use of BR and saturated TPS elastomers makes it possible to increase the stiffness and thus to improve the handling performance of the tires, without adversely affecting the hysteresis and therefore the rolling resistance of these tires.
