Tyre tread

A tire comprising a tread formed of at least a rubber composition, wherein the rubber composition includes:

• 50 to 100 phr of a first diene elastomer bearing a single SiOR function, R being hydrogen or a hydrocarbon radical;
• 105 to 150 phr of silica;
• less than 10 phr of carbon black;
• a plasticizing system that 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,
• wherein a total content A+B is between 50 and 80 phr, and
• wherein the composition comprises no elastomer other than the first diene elastomer and an optional second diene elastomer, the optional second diene elastomer being a polybutadiene or butadiene copolymer.
