ClearOn-Road Vehicle Measurement of Tire Wear Particle Emissions and Approach for Emission Prediction
An instrumented measurement vehicle was developed to quantify tire wear particle emissions under real-world on-road conditions, identifying key driving parameters such as speed, load, and cornering that govern emission rates. The study supports the development of emission factors and regulatory standards for non-exhaust tire-derived microplastic pollution.
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.
Assessing regional emissions of vehicle-based tire wear particle from macro-to micro/nano-scales with pandemic lockdowns and electromobility scenarios implications
Researchers developed a data-driven probabilistic model to estimate regional tire wear particle emissions across different land use scenarios, incorporating vehicle fleet data, driving patterns, and emission factors. Modeling suggested that tire wear particles represent a substantial and underappreciated pathway for microplastic entry into the atmosphere, with implications for both human health and environmental policy.
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.
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.
Modelled atmospheric concentration of tyre wear in an urban environment
Researchers modeled airborne concentrations of tire wear particles — tiny plastic-containing fragments released when vehicle tires rub against road surfaces — across Stockholm, finding that these microplastic particles are widespread in cities and make up 4–6% of total air particle pollution, with concentrations highest near busy highways and in narrow street canyons.
Characteristics of Vehicle Tire and Road Wear Particles’ Size Distribution and Influencing Factors Examined via Laboratory Test
Researchers conducted laboratory tests to characterize the size distribution of tire and road wear particles under various conditions. The study found that factors such as driving speed, tire composition, and road surface characteristics significantly influence the size and quantity of wear particles released, which are a growing source of microplastic pollution.
Static modelling of the material flows of micro- and nanoplastic particles caused by the use of vehicle tyres
Researchers modeled the flow of tyre wear particles in Austria, finding that about 6% of tyre rubber is released as wear particles into the environment each year, with emissions entering air, soil, and surface water. The study estimated that of the 21,200 tonnes released annually, about 6% are microscale particles and 0.3% are nanoscale, and concluded that reducing overall vehicle mileage would be the most effective way to cut these emissions.
Concentrations of tire wear microplastics and other traffic-derived non-exhaust particles in the road environment
Researchers measured actual environmental concentrations of tire wear microplastics and other traffic-derived non-exhaust particles in a rural highway setting, providing field-based data to complement the theoretical estimates that dominate current literature.

This study developed a parametrized and regionalized inventory model for tire and road wear particles for use in life cycle assessment, addressing the limitations of current emission factor estimates that do not capture regional differences in vehicle use and road conditions. The model provides more accurate and geographically resolved TRWP emission estimates for environmental impact accounting.

Tire Wear and Pollutants: An Overview of Research
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.

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.

Contribution of Road Vehicle Tyre Wear to Microplastics and Ambient Air Pollution
This review finds that tire wear from road vehicles contributes one-third to one-half of all microplastics released unintentionally into the environment, with passenger cars generating about 110 milligrams per kilometer driven. Most tire particles end up in soil, but a portion becomes airborne, contributing 5-30% of road transport particulate matter emissions. Since the smallest tire particles can be inhaled, this is a significant and often overlooked source of daily microplastic exposure for people living near roads.
