Provided is a rubber composition that contains a rubber component having excellent cold flow resistance and has improved low loss property and wear resistance as compared to conventional ones. The rubber composition comprises: a modified conjugated diene-based polymer having a hydroxyl group at a terminal; and at least one of a natural rubber or a polyisoprene rubber. The modified conjugated diene-based polymer preferably has a cis-1,4 bond content of 95% or more; the modified conjugated diene-based polymer preferably has a molecular weight distribution (Mw/Mn) of 2.5 or less; and a content of the modified conjugated diene-based polymer in a rubber component is preferable to be 20 mass % or more.
