ClearMethods for laboratory-generation and physico-chemical characterisation of tyre wear particles
Researchers developed a lab method to generate tire wear particles using a friction machine and then identified a suite of chemical compounds that could serve as reliable markers for detecting these particles in environmental samples. Tire wear is one of the largest single sources of microplastic pollution globally, yet quantifying it in the environment has been hampered by the lack of agreed marker compounds. This work lays groundwork for standardized monitoring of tire particle pollution in soils and waterways.
A Tiered Quantification and Source Mapping Framework for Tire Wear Particle Analysis in Environmental Matrices
Researchers developed an improved method for quantifying tire wear particles in environmental samples using pyrolysis gas chromatography-mass spectrometry based on real tire tread composition. The approach achieved 94-113% accuracy, a significant improvement over previous methods, and includes a tiered framework for distinguishing tire-derived signals from other interference. This methodology enables more reliable tracking of tire wear particles, a major but often underestimated source of microplastic pollution.
Quantification of tire wear particles in road dust based on synthetic/natural rubber ratio using pyrolysis-gas chromatography–mass spectrometry across diverse tire types
Researchers developed an improved method for measuring tire wear particles in road dust that accounts for differences in rubber composition across tire brands and types.

The refined approach provides more accurate measurements of this major source of microplastic pollution from road traffic.

What is known and unknown concerning microplastics from tyre wear?
This review synthesizes current knowledge on tyre wear particles (TWPs) as a major source of road-traffic microplastics, covering how particle generation, transport pathways, and environmental fate depend on tyre composition, road characteristics, and weather. A key finding is that while TWPs can be identified in environmental samples, quantifying them precisely remains difficult and expensive—a gap that must be closed to accurately assess human and ecological exposure.
Chemical Leaching from Tire Wear Particles with Various Treadwear Ratings
Researchers investigated how tire treadwear ratings affect chemical leaching from tire wear particles, finding that benzothiazole compounds leached at different rates depending on tire type, with an additional derivative (2-mercaptobenzothiazole) detected by high-resolution mass spectrometry. The findings suggest that using benzothiazole alone as a quantification marker for tire wear particles can lead to inaccurate estimates of environmental contamination.

The adapted methods were validated with road dust samples and confirmed by electron microscopy and pyrolysis mass spectrometry.

Tire Wear Monitoring Approach for Hotspot Identification in Road Deposited Sediments from a Metropolitan City in Germany
Researchers developed a systematic road-sampling approach to identify urban hotspots for tire-and-road wear particles (TRWP) — a major category of microplastic pollution — by sweeping road-deposited sediments at six inner-city monitoring sites. Curves and traffic-light zones accumulated 8x and 3x more styrene-butadiene rubber (a TRWP marker) than straight road sections, respectively. Since tire wear is one of the largest sources of microplastics entering waterways via road runoff, this hotspot mapping method can inform targeted mitigation measures.
