ClearMechanism of microplastic and nanoplastic emission from tire wear
Scientists showed that normal tire wear produces two distinct populations of plastic particles: smaller airborne nanoplastics that stay suspended in the air, and larger microplastics that settle to the ground. Nanoplastic emissions increase dramatically with vehicle speed and weight, and electric charge keeps the smallest particles floating in the air where they can be inhaled. This research identifies tire wear as a major and previously underappreciated source of breathable nanoplastic pollution.

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.

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.
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. They found that increasing vehicle weight due to electrification trends and growing traffic volumes are driving higher emissions, while no regulations currently exist for tire wear. The study provides methods needed for tracking changes in tire-related microplastic pollution and supporting future environmental impact assessments.
Are vehicle tires major contributors to microplastic emissions into the China seas? A simple model perspective
Researchers developed a model to estimate annual microplastic emissions from vehicle tires into China's marine environment.

This review provides an overview of tire road and wear particles as a major source of microplastic emissions, examining both experimental and mathematical approaches to measuring tire wear.

Environmental occurrence, fate, impact, and potential solution of tire microplastics: Similarities and differences with tire wear particles
This review examines tire microplastics, one of the most abundant types of microplastics in the environment, which come from tire wear on roads, recycled tire rubber, and tire repair dust. These particles carry a complex mix of chemicals including heavy metals and organic pollutants that can harm aquatic and soil organisms. Since tire microplastics end up in waterways and soil near roads, they represent a significant but often overlooked source of human microplastic exposure.

This work lays groundwork for standardized monitoring of tire particle pollution in soils and waterways.
