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 its 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 Michelin's 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.
