Oxygen Consumption Rate in New and In-Service BFGoodrich P195/65R15 Tires

摘要

This report is the second in a series of scientific reports intended to provide an understanding of the chemical reactions responsible for the degradation of light vehicle tires during on-vehicle service. The report series was used to guide the agency's development of a laboratory-based accelerated service life test for light vehicle tires ('tire aging test'). This particular report examines the changes observed in the fixed oxygen level, elongation-to-break, and inter-belt peel adhesion of the belt-coat compound of an original equipment BFGoodrich tire model after varying lengths of service and accumulated mileages in Phoenix, Arizona.
