ClearRealistic 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.
Development of a parametrized and regionalized life cycle inventory model for tire and road wear particles
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.

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.
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.
Comprehensive approach to national tire wear emissions: Challenges and implications
Researchers developed a comprehensive approach to estimate national tire wear emissions, which are a major source of microplastics in the environment.
