A tire, which has an improved grip on wet ground, includes a tread formed of at least 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 hundred 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 5 and 60 phr of a hydrocarbon resin having a Tg above 20° C.; and a content B of between 5 and 60 phr of a liquid plasticizing agent. A total content A+B is greater than 45 phr. The rubber composition optionally includes 0 to 80 phr of a second diene elastomer.
