<p>The present invention provides a rubber composition which makes it possible to improve the handling stability, ride comfort, and elongation at break in a balanced manner and at the same time to achieve satisfactory processability and fuel economy; and also provides a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition including a masterbatch that includes: a modified natural rubber with a phosphorus content of 200 ppm or less; and microfibrillated plant fibers. The rubber composition preferably has a ratio (E*a/E*b) of a complex modulus E*a in an extrusion direction to a complex modulus E*b in a perpendicular direction to the extrusion direction, both measured at a temperature of 70°C and a dynamic strain amplitude of 2% under an initial elongation of 10%, of 1.05 to 6 .00, wherein the complex modulus E*a is 7 to 100 MPa.</p> |
