The rubber composition comprises more of the second styrene butadiene rubber than of the first styrene butadiene rubber. The rubber composition further comprises 5 phr to 30 phr or from 15 phr to 25 phr of at least one member selected from the group consisting of natural rubber and synthetic polyisoprene rubber; 135 phr to 200 phr of silica; and at least 55 phr of at least one hydrocarbon resin comprising at least one terpene resin which has a glass transition temperature of at least 30°C. Also, a tire (1) having a component, preferably a tread (10), comprising such a rubber composition is disclosed.",
