Synopsis

This study develops a reliable method for quantifying tyre wear and airborne tyre wear particles (TWPs) under controlled laboratory conditions. Using a flow-optimised drum test bench with advanced particle measurement systems, the setup minimizes background emissions and enables precise analysis. Results show talc powder, used for degumming, increases tyre wear rates but complicates particle measurements. Distinctions between talc and TWPs were achieved through size distribution and force correlation analysis, revealing airborne TWPs contribute less than 5% to total tyre wear emissions.
