Zusammenfassung:	A tire having an improved wet grip, in particular for a passenger vehicle, a van, or two-wheel vehicle, includes a tread of which includes a rubber composition. The rubber composition includes at least (phr meaning parts by weight per hundred parts of elastomer): as a first diene elastomer, from 55 to 95 phr of natural rubber or synthetic polyisoprene; as a second diene elastomer, from 5 to 45 phr of a polybutadiene or butadiene copolymer having a Tg greater than −70° C.; as a reinforcing filler, from 60 to 90 phr of an inorganic filler; as a plasticizer, more than 5 phr of a thermoplastic hydrocarbon resin exhibiting a Tg greater than 20° C.; and optionally, from 0 to 20 phr of a plasticizing agent, which is a liquid at 23° C.
