ClearTyre wear particles: an abundant yet widely unreported microplastic?
Researchers collected tire wear particles from roadside drains and natural environments near a major UK road, finding that these particles are abundant and widespread yet frequently undetected in environmental monitoring, suggesting tyre wear is a major but under-reported microplastic source.
Tire and road wear particles contamination in infiltration ponds sediments: occurrence, spatial variability, size distribution and correlation with metals
Researchers examined tire and road wear particle (TRWP) contamination in infiltration pond sediments, characterizing their occurrence, spatial variability, size distribution, and correlation with heavy metals to assess the pollution dynamics of these road-derived particles in urban drainage systems.
Microplastics and tyre wear particles infiltration in the soil of a roadside biofiltration swale
Researchers investigated the infiltration of microplastics and tyre wear particles into soil along a roadside biofiltration swale, assessing the extent to which these particles migrate from the road surface into subsurface soils under real-world conditions.
Quantifying pathways of tyre wear into the environment.
Researchers conducted the first national-scale spatial analysis of tyre wear particle (TWP) pathways in the UK, estimating that 79.5 kilotonnes of TWPs are released annually with 23-34 kt reaching surface waters, 18.5-30.2 kt deposited on roadsides, and 1.3-6.7 kt entering the atmosphere.
Impregnation levels and gradient of tire wear particle content of surface soils adjacent to a major road
Researchers assessed the impregnation levels and spatial gradient of tire and road wear particle (TRWP) contamination in surface soils adjacent to a major road, investigating how proximity to the road surface affects the degree of microplastic loading in roadside soil profiles. The results showed significant TRWP concentrations in soils closest to the road, with contamination gradients extending laterally into adjacent land, confirming roadside soils as durable repositories of tyre-derived microplastics.
Assessment of fine and coarse tyre wear particles along a highway stormwater system and in receiving waters: Occurrence and transport
Researchers tracked tire wear particles through a highway stormwater drainage system in Sweden and found contamination at nearly every sampling point, with concentrations reaching up to 17 milligrams per liter in water. A significant portion of the particles were very small, in the 1.6 to 20 micrometer range, which are harder to filter out and more likely to travel long distances. The study highlights that tire wear is a major and often overlooked source of microplastic pollution reaching waterways.
Determination of tire wear markers in soil samples and their distribution in a roadside soil
Researchers developed a thermal extraction method to measure tire wear particles in roadside soil, finding concentrations up to 15,898 mg/kg with most particles accumulating in the topsoil within 2 meters of the road surface.
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.
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.
Tire wear particles concentrations in gully pot sediments
Researchers measured tire wear particle (TWP) concentrations in gully pot sediments, developing analytical methods to quantify this major microplastic source in road runoff as it enters urban drainage systems before reaching the broader environment.
Identification, classification and quantification of microplastics in road dust and stormwater
Researchers identified and quantified microplastics in road dust and stormwater, finding significantly higher concentrations in industrial areas compared to residential zones, with tire wear particles and polyethylene fragments being the most common types.
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.
The transport of tyre wear particles in rivers, with a focus on settling and resuspension
Researchers investigated the transport dynamics of tyre and road wear particles (TRWPs) in river systems, with particular focus on settling and resuspension processes in aquatic environments, and explored pathways toward groundwater, addressing a gap in understanding TRWP fate in the environment.
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.

Relevance of tyre wear particles to the total content of microplastics transported by runoff in a high-imperviousness and intense vehicle traffic urban area.
Researchers characterized microplastics and tire wear particles (TWPs) transported by urban stormwater runoff in a highly impervious catchment, finding that TWPs made up a substantial fraction of the total microplastic load in sediments of a stormwater detention reservoir. The study underscores the contribution of road traffic to microplastic pollution entering waterways.
Tire wear particles in the aquatic environment - A review on generation, analysis, occurrence, fate and effects
Researchers reviewed available science on tire wear particles (TWP) — tiny fragments shed from tires during driving — finding that Europe alone generates over 1.3 million tonnes per year, but critical data on environmental concentrations, transport to waterways, and aquatic toxicity remain too limited for robust ecological risk assessment.
Features of the highway road network that generate or retain tyre wear particles
This study analyzed highway road network features that contribute to tyre wear particle generation and retention, finding that road curvature, gradient, and surface texture are key factors influencing where tyre-derived microplastics accumulate along road corridors.
Tyre Wear Particles: Emissions and Distribution in Soil and Stormwater Systems in Near Road Environments
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.

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.
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.
