<p>The present invention provides a rubber composition comprising: a rubber constituent containing polybutadiene and diene rubber or olefin rubber that is immiscible with the polybutadiene; and a filler, wherein when the Mooney viscosity (ML1+4/100°C) of the polybutadiene is ML(I) and the Mooney viscosity (ML1+4/100°C) of the diene rubber or olefin rubber that is immiscible with the polybutadiene is ML(II), the relation of ML(I) = ML(II) is satisfied, the crashworthiness is excellent without decreasing durability such as wear resistance of the tire, the good working property can be achieved, and further the decrease of rolling resistance of tire can be achieved. The present invention also provides a method of producing the rubber composition, and a tire using the rubber composition.</p> |
