<p>A snow tyre with an improved grip on wet ground includes a tread formed of a rubber composition. The rubber composition includes: 20 to 100 phr of a first diene elastomer bearing at least one SiOR function, with R being hydrogen or a hydrocarbon radical, and with phr referring to parts by weight per hunder parts of elastomer; 100 to 160 phr of a reinforcing inorganic filler; and a plasticizing system. The plasticizing system includes: a content A of between 10 and 60 phr of a hydrocarbon resin having a Tg above 20° C.; and a content B of between 10 and 60 phr of a liquid plasticizing agent. A total content A+B is greater than 50 phr. Optionally, the rubber composition also includes 0 to 80 phr of a second diene elastomer.</p> |
