Development of an Aged Tire Durability Standard - Determination of Time and Temperature Parameters for Accelerated Laboratory Static Aging

During the first phase (Phase 1) of aged durability test development, static oven aging of tires was selected as the preferred method of accelerated laboratory aging. representative material property changes and warranted further study. The objective of this follow-up Phase 2 oven aging study was to identify preferred temperatures and times (or ranges) for the accelerated oven aging of tires, which could yield material property changes similar to those observed for in-service tires. These studies were conducted on three tire models. Conclusions and recommendations for subsequent validation across a broad spectrum of consumer tire types were reached.
