A rubber composition comprises, per 100 parts by weight of a diene rubber containing from 35% to 89% by weight of a modified conjugated diene polymer rubber and from 11% to 40% by weight of a butadiene rubber, from 3 to 60 parts by weight of an aromatic modified terpene resin and from 100 to 150 parts by weight of a filler. A ratio of the compounded amount of the aromatic modified terpene resin to the compounded amount of the butadiene rubber is from 0.5 to 1.3. An aromatic vinyl unit content is from 38% to 48% by weight of the modified conjugated diene polymer rubber, with a vinyl unit content being from 20% to 35% by weight of the modified conjugated diene polymer rubber, and a weight-average molecular weight of the modified conjugated diene polymer rubber being from 600,000 to 1,000,000.
