ClearCharacterization of airborne tire particle emissions under realistic conditions on the chassis dynamometer, on the test track, and on the road
Researchers developed a new tire and road wear particle (TRWP) sampling system and characterized airborne emissions under real-world conditions on a chassis dynamometer, test track, and public road. Emissions showed a bimodal size distribution with dominant modes at ~10 nm and 270 nm, with SEM/EDS revealing two particle formation mechanisms and confirming tire rubber as a major source of ultrafine airborne particles.

Realistic evaluation of tire wear particle emissions and their driving factors on different road types
This study measured tire wear particle (TWP) emissions under realistic driving conditions on different road types and identified the key driving factors affecting emission rates. Tire wear particles are a major category of microplastic pollution in road runoff, and this data is needed to estimate their contribution to environmental contamination.

Characteristics of Real-world Non-exhaust Particulates from Vehicles
Researchers characterized non-exhaust particulate emissions from vehicle tire and road wear, collecting atmospheric PM samples with a high-volume quartz filter sampler and using pyrolysis-GC/MS to analyze tire rubber markers including polycyclic aromatic hydrocarbons and heavy metals, quantifying the contribution of tire-brake-road wear particles to urban air pollution.
Analytical Investigation of Tire Induced Particle Emissions
This automotive engineering study measured the size distribution of fine dust particles (under 10 micrometers) generated by tire wear, finding that tire-derived particles represent a significant non-exhaust source of urban particulate matter. As electric vehicle adoption reduces exhaust emissions, tire and brake wear particles will become a proportionally larger component of urban air pollution. These tire wear particles are also a major source of microplastic contamination in road runoff.
Comparison of traffic-related micro- and nanoplastic concentrations at three urban locations
Researchers measured airborne tire and road wear particles (microplastics shed from vehicle tires) at a busy urban road, a highway, and a park, finding rubber particle concentrations were 2-5 times higher near traffic compared to the park, with levels closely tracking other traffic pollutants like black carbon.
Vehicle Emission Models and Traffic Simulators: A Review
This review surveys vehicle emission models and traffic simulation tools used to estimate air pollution from road traffic. While focused on exhaust emissions, the methods discussed are relevant to understanding non-exhaust pollution like tire wear microplastics, which are released in large quantities from vehicle tires. Better emission modeling could help quantify the full scope of traffic-related microplastic pollution in urban areas.
Tyre and road wear particles from source to sea
Researchers traced tyre and road wear particles (TRWP) — tiny rubber fragments shed when vehicles brake and turn — from urban roads into marine sediments, finding that softer tyres with more natural rubber shed more particles and that TRWP concentrations drop sharply with distance from cities. Unlike lighter microplastics that drift widely, TRWP sink quickly and accumulate near urban coastlines, threatening nearshore sediment ecosystems.

Researchers developed a detailed model for estimating tire and road wear particle emissions, a major but often overlooked source of microplastics from vehicle traffic. The model accounts for nine key factors including road texture, driving behavior, temperature, and tire type, and can generate estimates at both individual vehicle and national scales. The study found that road surface roughness, aggressive driving, and wet conditions are the biggest drivers of large particle emissions, while temperature and vehicle load most affect fine particle release.

While the risk from inhaling these particles appears low, the potential health effects from ingesting them through the food chain remain largely unknown.
