TYRE TREAD

摘要

The present invention concerns a tyre tread that comprises a rubber composition made of at least: an elastomer matrix including more than 50 wt % of a first diene elastomer with a silanol function and a pendant amine function; a silica in a proportion of 120 to 140 phr; a coupling agent; a plasticising system including: in a proportion A of 5 to 60 phr, a hydrocarbon resin having a Tg higher than 20 °C; and in a proportion B of 0 to 60 phr, a liquid plasticising agent; wherein the total proportion A+B is no lower than 60 phr, and preferably 60 to 90 phr. The tread of the invention makes it possible to improve the compromise between grip on wet ground and grip on dry ground with low rolling resistance.
