The novel approach to deconvolute wear rate into different components

This paper explores the idea of deconvoluting the measured wear rate of a tire tread compound into different components such as abrasive wear and smear wear with the ultimate goal of elucidating tire tread wear phenomena. A custom-built surface abrasion machine was used to investigate the wear behavior of tire tread compounds made from either synthetic polyisoprene rubber or styrene-butadiene rubber, reinforced with either carbon black or silica. The findings of this research will be discussed in the contexts of compound design and optimization, wear testing improvements and wear modeling.
