摘要： The invention provides rubber compositions comprising: a diene rubber component; and a filler system, wherein the filler system comprises: a first silica which is surface-functionalised by the introduction of one of more functional groups and has a BET specific surface area of from 250 to 310 m2/g and a CTAB specific surface area of from 230 to 285 m2/g; and a second silica which is not surface-functionalised and has a BET specific surface area of from 60 to 120 m2/g and a CTAB specific surface area of from 55 to 105 m2/g. The rubber compositions are particularly suitable for use in the production of tire components, in particular tire treads.
