VULCANIZABLE RUBBER COMPOSITION FOR A PNEUMATIC TIRE

A vulcanizable rubber composition and its use in a tire or an article of manufacture is disclosed. The vulcanizable rubber composition comprises: from 30 to 90 phr of a first functionalized styrene-butadiene rubber having a glass transition temperature Tg1 ranging from -70 to -50 °C; and from 10 to 50 phr of a second functionalized styrene-butadiene rubber having a glass transition temperature Tg2 ranging from - 110 to -70°C. Tg2 minus Tg1 is at least 10 °C. It further comprises from 0 to 40 phr of at least one additional elastomer; from 50 to 150 phr of silica; from 0 to 50 phr of a hydrocarbon resin; and from 10 to 50 phr of an oil.
