The present invention relates to a rubber composition for a side wall or a clinch comprising a rubber component containing: (a) 20 to 60 % by weight of polybutadiene rubber containing 2.5 to 20 % by weight of crystal 1,2-syndiotactic polybutadiene, (b) 5 to 40 % by weight of a tin modified polybutadiene rubber polymerized by a lithium initiator, wherein the amount of a tin atom is 50 to 3000 ppm, the amount of vinyl bonds is 5 to 50 % by weight and molecular weight distribution (Mw/Mn) is at most 2, and (c) 20 to 75 % by weight of a rubber except for (a) and (b).",
