FOAMING RUBBER COMPOSITION AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To improve both abrasion resistance and on-ice performance by independently controlling a foam rate and a foam diameter. SOLUTION: A rubber component including at least one kind of natural rubber and synthetic rubber is foamed with azodicarbonamide as a foaming agent and benzenesulfinic sodium or also urea as a foaming assistant, and this foaming rubber is applied to a tread of this pneumatic tire.
