ClearDevelopment 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.
Dynamic probabilistic material flow analysis of rubber release from tires into the environment
A dynamic material flow analysis model estimated the annual and cumulative release of rubber from vehicle tires into the environment via road wear, finding that tire rubber represents a substantial fraction of total microplastic pollution in terrestrial and aquatic systems. The study helps quantify this important but often overlooked microplastic source.

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.

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 - A calculation of generation, transport and release to water and soil with special regard to German roads
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.
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.
Pollution from Transport: Detection of Tyre Particles in Environmental Samples
This study reviews tyre wear particles as a major but underestimated source of microplastic pollution from road transport, describing methods for detecting these particles in environmental samples including road dust, waterways, and soils. The authors call for greater regulatory attention to tyre-derived emissions alongside other transport-related pollutants.

Researchers conducted a multi-scale investigation of tyre wear particle emissions in Sweden, characterizing their distribution in roadside ditches and stormwater systems and developing a national emissions estimation methodology using vehicle-specific factors. Passenger cars were identified as the largest contributor at 55% of total tyre wear particle emissions, and the study evaluated the effectiveness of selected mitigation strategies.
Wear and Tear of Tyres: A Stealthy Source of Microplastics in the Environment
This paper compiles existing knowledge on tire wear as a major but often overlooked source of microplastics, estimating global per-person emissions at about 0.8 kilograms per year. Tire particles enter waterways, air, and soil, with an estimated 5-10% of ocean plastic pollution originating from tire wear. The study calls for increased awareness and creative solutions to address this stealthy yet substantial contributor to microplastic contamination.
Measures to reduce the spread of microplastic particles from tyre wear : On vehicles, on the road and in the roadside environment
Researchers reviewed measures to reduce the spread of microplastic particles from tyre wear at the vehicle, road, and roadside environment levels, examining the transport pathways via air, water, and snow and the risks these persistent, potentially toxic particles pose to ecosystems and human health.
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.

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.
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.
Mechanism 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.
A review of rubber tyre derived micro- and nanoplastics: fate, impact and risks
This systematic review examines microplastics generated from rubber tire wear, which are a major but often overlooked source of microplastic pollution. Tire particles spread through air, stormwater, and wastewater to contaminate both land and water. This is an important human health concern because tire-derived microplastics contain toxic chemicals and are found in the air people breathe and the water they drink.

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.
