Abstract

A vulcanizable rubber composition for treads of vehicle tires, comprises: a) a cross-linkable unsaturated chain polymeric base including 1 to 40 phr of at least an unsaturated chain modified polymer including polar groups, b) 15 to 100 phr of a silica-based reinforcing filler including superficial hydroxyl groups, c) 0.5 to 5 parts by weight per each 100 parts by weight of said silica-based reinforcing filler of at least a sulfur-containing stabilizing agent of the vulcanization network, d) an effective amount of at least one vulcanizing agent. Advantageously, said rubber composition allows to obtain a tread with a reduced rolling resistance, a good wear resistance and a good wet-skid resistance, while reducing to a minimum the production problems associated to the use of silica as reinforcing filler.
