RUBBER COMPOSITION FOR SIDEWALL, INSULATION OR BREAKER CUSHION, PRODUCTION METHOD THEREOF, AND PNEUMATIC TIRE

摘要

The present invention provides a rubber composition for a sidewall, an insulation, or a breaker cushion, which can achieve both excellent fuel economy (low heat build-up) and high flex crack growth resistance while having processability excellent enough to eliminate the need for mastication, and also provides a pneumatic tire produced using the rubber composition. The present invention relates to a rubber composition for a sidewall, an insulation, or a breaker cushion, including: a rubber component that contains a modified natural rubber with a phosphorus content of 200 ppm or less; and carbon black and/or a white filler.
