Abstract
The problem to be solved by the present disclosure is to provide a rubber composition that achieves both thermal degradation resistance and breaking resistance. The solution is a rubber composition including a diene-based rubber (A), a heterocyclic compound (B) having a six-membered aromatic heterocyclic ring, a metal salt (C) (excluding metal oxides, metal carbonate salts, and metal salts of fatty acids with 10 or more carbon atoms), an organic peroxide (D), and a carbon black (E). The mass ratio (D/C) of the organic peroxide (D) to the metal salt (C) is preferably 0.1 to 10.
