The present invention provides a method for manufacturing a rubber composition, the method making it possible to obtain a rubber composition having exceptional reinforcing properties by improving the dispersivity of fibers in a rubber component when a rubber is compounded with the fibers. The present invention also provides a rubber composition obtained using the method, a vulcanized rubber, and a tire. The present invention is a method for manufacturing a rubber composition containing short fibers. The method includes a liquid-dispersion preparation step for preparing a short-fiber liquid dispersion by adding short fibers to a liquid, a mixed liquid dispersion preparation step for admixing at least one dispersant selected from the group consisting of carbon black and an inorganic compound into a short-fiber liquid dispersion to prepare a mixed liquid dispersion, a mixing step for mixing the mixed liquid dispersion and a latex rubber to prepare a rubber/short-fiber liquid mixture, and a drying step for drying the rubber/short-fiber liquid mixture to obtain a rubber composition.
