The present invention provides a rubber composition based on at least one diene elastomer and a reinforcing filler (the reinforcing filler comprises at least carbon black and an inorganic filler and an inorganic filler content is 50 parts by weight or less per 100 parts of the elastomer). Wherein, the composition is obtained from a first masterbatch comprising at least one first diene elastomer and carbon black, the masterbatch having a degree of dispersion of the carbon black in the elastomer matrix to a Z value of at least 90, To the masterbatch, the inorganic filler and at least one second elastomer, which is the same or different from the first elastomer, is added, and also relates to a method for producing the composition. |
