Biesse has been working for Michelin for 25 years. After several years in the numerical analysis domain, he started working in tire performance analysis, first for noise then for wear and rolling resistance, later becoming manager of the performance analysis team in charge of wear and rolling resistance. He is now a fellow (expert) in tire physics and performance modelization.

Presentation

Refined characterization of tire road wear particle emissions

Michelin is actively working to reduce the environmental impact of tires. Amongst other important levers like energy efficiency, longevity and quantity of materials used, TRWP is a key lever in order to achieve our goals. Measuring TRWP quantity and size distribution – and particularly the small particles (below 10 µm) – is a technical challenge. The improvement of characterization methods used in Michelines measurements enables the further refinement of the evaluation of TRWP emissions, reducing the bias faced by many studies. This and other progress will be presented.
