Oven aging has been suggested as an approach to aged endurance tire testing for passenger and light truck tires. Oxidative crosslinking has been shown to be the major aging mechanism in the beltcoat of these tires. Some key points were examined and reported herein to aid this development. This understanding may help designing aged tire tests which better simulate field (normal service) conditions. The following questionswere examined by aging wirecoat compound extracted from a passenger tire. (1) What is the effect of aging temperature on the crosslink structure and properties? (2) If diffusion of oxygen slows during aging, what happens to the crosslink structure and properties? (3) What is the effect of strain (static or dynamic) during aging on the crosslink structure and properties?
