The present invention relates to a tire tread that comprises a rubber composition based on at least: an elastomer matrix comprising more than 50 wt % of a first diene elastomer bearing a silanol function and a pendent amine function; a silica at a level between 120 and 140 phr; a coupling agent; and a plasticizer system comprising a hydrocarbon-containing resin having a Tg above 20° C. according to a content A ranging from 5 to 60 phr, a hydrocarbon-containing resin having a Tg above 20° C. and a liquid plasticizer according to a content B ranging from 0 to 60 phr, a liquid plasticizer, it being understood that the total level A+B is at least equal to 60 phr, preferably ranging from 60 to 90 phr. The tread according to the invention makes it possible to improve the compromise between wet grip and dry grip of a tire with low rolling resistance. |
