The present invention provides a rubber composition for antire, in which gripping performance and abrasion resistance arenimproved in a balanced manner, and a tire using the same. Specifically,nthe present invention provides a rubber composition for a tirencomprising 5 to 200 parts by weight of a low molecular weight aromaticnvinyl-conjugated diene copolymer having a specific aromatic vinylncontent and weight average molecular weight, based on 100 parts bynweight of a rubber component containing aromatic vinyl-conjugatedndiene copolymer, a rubber composition for a tire comprising 5 to 200nparts by weight of an olefin-conjugated diene-aromatic vinyl copolymernbased on 100 parts by weight of a diene rubber component, and a tirenusing the same. |
