The purpose of the present invention is to provide a rubber composition for a base tread being excellent in fuel efficiency. In the rubber composition for a base tread, a dynamic elastic modulus E* (MPa) and a loss tangent tan´ which are measured at a temperature of 70°C, an initial strain of 10% and a dynamic strain of 2% satisfy the following general formulae (1) to (3), and a strength at break TB (MPa) and an elongation at break EB (%) which are measured according to JIS K6251 satisfy the following general formulae (4) and (5). E * / tan´ ¥ 25 2.0 ¤ E * ¤ 8.0 tan´ ¤ 0.08 EB ¥ 350 TB × EB ¥ 8500
