  • Publication number: 20120214933
    Abstract: The present invention relates to a tyre, 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 tyres, without adversely affecting the hysteresis and therefore the rolling resistance of these tyres.
