Zusammenfassung:	A vulcanizable rubber composition for use in a tread of a pneumatic tire is disclosed. The rubber composition comprises, based on 100 parts by weight of elastomer (phr),(A) from 20 to 100 phr of a solution polymerized styrene-butadiene rubber having a glass transition temperature (Tg) in a range of from -85 °C to -50 °C;(B) from 0 to 40 phr of a natural rubber or synthetic polyisoprene;(C) from 0 to 30 phr of a cis-1,4 polybutadiene having a Tg in a range of from - 110ºC to -90ºC;(D) from 0 to 50 phr of a process oil;(E) from 20 to 80 phr of a hydrocarbon resin having a Tg of at least 30 °C; and(F) from 90 to 150 phr of silica.
