The present invention is a method for producing a vulcanized rubber composition that contains a rubber component containing a polyisoprene rubber, and a syndiotactic 1,2-polybutadiene, wherein the syndiotactic 1,2-polybutadiene and the polyisoprene rubber are kneaded at a temperature higher by 10 to 100°C than the melting point of the syndiotactic 1,2-polybutadiene, and the resultant unvulcanized rubber composition is vulcanized at a temperature falling within a range of the melting point of the syndiotactic 1,2-polybutadiene ± 15°C. The method improves the crack growth resistance of the vulcanized rubber composition.
