Rubber composition for pneumatic tyre and pneumatic tyre produced therefrom

A rubber composition for a pneumatic tyre, comprising:

• a copolymer of styrene and butadiene (SBR), optionally functionalised, having a glass transition temperature (Tg) of less than −20° C.;
• a plasticiser system comprising one or more hydrocarbon resins, wherein the total amount of hydrocarbon resin in the rubber composition is at least 45 phr;
• and
• a filler system comprising one or more silicas, including a first silica having a CTAB surface area of greater than 150 m2g−1, and optionally one or more additional fillers, wherein the first silica is present in the rubber composition in an amount of at least 110 phr,
• wherein the ratio of the total amount of the filler system to the total amount of the plasticiser system on a parts per hundred rubber (phr) basis in the rubber composition is at least 1.75:1.
