Abstract:
The present invention relates to a tire having a tread comprising a rubber composition that comprises at least: as a first diene elastomer, between 5 and 25 phr of a styrene-nitrile-butadiene terpolymer (SNBR) having a nitrile monomer content between 4 and 18% by weight; a second diene elastomer other than SNBR; a reinforcing filler; a liquid plasticizer, the glass transition temperature of which is below −20° C. The invention makes it possible to improve the properties of rolling resistance and of grip on wet ground of tire treads.
