Tire with rubber tread of cap/base construction wherein the tread base rubber composition contains combination of anti-reversion agents
摘要:
The invention relates to a tire with rubber tread of cap/base construction. The tread base underlies the tread cap. The tread base is relatively thick, namely at least 50 percent of the thickness of the tread cap. It is desired that the tread base rubber composition contains a significant amount of sulfur to enhance physical properties of the tread base. The tread base rubber composition contains a combination of anti-reversion agents to counteract a tendency for reversion of physical properties of the tread base which is relatively thick as compared to the tread cap. The combination of anti-reversion co-agents is 1,3-bis-(citraconimidomethyl)benzene and hexamethylene 1,6-bis(thiosulfate), disodium salt, dehydrate thereby substantially maintaining the integrity of physical properties of the tread base, reduced tire operating temperature, as well as retarded or eliminated groove cracking in the tread cap has been observed.
