Abstract
The present invention provides a rubber composition for a tire, in which gripping performance and abrasion resistance are improved in a balanced manner, and a tire using the same. Specifically, the present invention provides a rubber composition for a tire comprising 5 to 200 parts by weight of a low molecular weight aromatic vinyl-conjugated diene copolymer having a specific aromatic vinyl content and weight average molecular weight, based on 100 parts by weight of a rubber component containing aromatic vinyl-conjugated diene copolymer, a rubber composition for a tire comprising 5 to 200 parts by weight of an olefin-conjugated diene-aromatic vinyl copolymer based on 100 parts by weight of a diene rubber component, and a tire using the same.
