Document Type and Number:
Japanese Patent JP7422487
Kind Code:
B2
Abstract:
A rubber composition allows suppression of cracking and discoloration of a tire surface. The rubber composition includes a rubber component (A), a quinoline age resistor (B) including a polymer of 2,2,4-trimethyl-1,2-dihydroquinoline, and N-phenyl-N'-(1,3-dimethylbutyl)-p-phenylenediamine (C). The content ratio of the quinoline age resistor (B) is 0.1 mass% to 1.5 mass% in terms of the total amount of the rubber composition. The total content ratio of dimers and trimers of the 2,2,4-trimethyl-1,2-dihydroquinoline in the quinoline age resistor (B) is 60 mass% or more.
