A tyre, which has an improved grip on wet ground, includes a tread formed of at least a rubber composition. The rubber composition includes: from 50 to 100 phr of a copolymer based on styrene and butadiene, e.g., a styrene/butadiene copolymer (SBR), with phr referring to parts by weight per hundred parts of elastomer; from 100 to 150 phr of a reinforcing inorganic filler, e.g., silica; and a plasticizing system. The plasticizing system includes: a content A of between 10 and 60 phr of a thermoplastic hydrocarbon resin exhibiting a Tg of greater than 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 includes from 0 to 50 phr of another copolymer, e.g., a diene elastomer such as a polybutadiene or natural rubber.
