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.
Tire Abrasion as a Major Source of Microplastics in the Environment
This study analyzed tire wear particles as a major source of microplastics in the environment, estimating that tire abrasion contributes a substantial fraction of total microplastic emissions globally and highlighting road runoff as a key delivery pathway to waterways.
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.

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.
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.
Shades of grey—tire characteristics and road surface influence tire and road wear particle (TRWP) abundance and physicochemical properties
A suite of experiments characterized how tire type, compound, and road surface properties influence tire and road wear particle (TRWP) size, morphology, and emission rates, finding significant variation across tire and road combinations relevant to predicting environmental exposure.
Types and concentrations of tire wear particles (TWPs) in road dust generated in slow lanes.
Road dust samples collected near traffic lights contained tire wear particles (TWPs), with the concentration and size distribution varying by location and traffic direction. Tire wear is one of the largest sources of microplastic pollution in urban environments, and these particles are carried into waterways by stormwater runoff.
Urban wash-off of tire wear particles
Researchers used a rainfall simulator to study how tire wear particles, an important class of microplastics, are washed off road surfaces during storm events. They found that low surface roughness, high rainfall intensity, and low slope produced the fastest and most complete mobilization of tire wear particles. The study reveals that larger tire particles moved faster than smaller ones, and flow depth was the most important factor governing wash-off behavior.
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.
Microplastics from tyre and road wear A literature review
This literature review examines microplastics generated from tire and road wear, identifying road traffic as a significant but often overlooked source of plastic pollution in urban runoff and waterways. The authors assess what is known about tire particle composition, environmental fate, and potential ecological effects.
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. The study notes that while tire wear particles are found in alarming amounts across various environments, they remain less studied than other microplastics, and calls for more accurate simulation models to predict tire wear emissions.

This study calculated that German roads generate 75,000 to 98,000 tons of tire and road wear particles annually, with a significant portion reaching surface waters and roadside soils. The findings highlight tire wear as a major but often overlooked source of microplastic pollution requiring better data and management strategies.
Microplastic and tyre wear particles at a highway: a case study from Norway
Researchers monitored microplastics and tire wear particles (tiny rubber fragments shed by vehicles) in air, road runoff, and road dust along a busy Norwegian highway, finding the highest concentrations in road dust and the lowest in air. The study demonstrates that traffic is a major source of microplastic pollution across multiple environmental pathways.

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.

Is road pavement wear a source of microplastics in stormwater runoff?
This study investigated whether road pavement wear is a measurable source of microplastics in stormwater runoff, distinct from the better-characterized tire wear contribution. Pavement-derived particles were identified in stormwater samples, confirming that road surface material itself contributes to microplastic loading in urban runoff alongside tire wear and other sources.
