ClearMicroplastics 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.

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.

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.
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.
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.
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.
On airborne tire wear particles along roads with different traffic characteristics using passive sampling and optical microscopy, single particle SEM/EDX, and µ-ATR-FTIR analyses
Researchers used passive sampling and advanced analytical techniques including SEM/EDX and micro-ATR-FTIR to characterize airborne tire wear particles along roads with different traffic volumes and speeds. The study found that tire wear particles, a major category of microplastic pollution, varied in concentration and composition depending on traffic characteristics, highlighting roadways as a significant source of airborne microplastic contamination.
Tyre 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.
Characterization of Airborne Microplastics Particles on Urban Roads: Types, Sizes, and Total Particles
Researchers collected airborne microplastic samples from urban road environments and characterized particle types, sizes, color distributions, and polymer compositions, finding tire-wear rubber and paint fragments alongside fiber and film fragments from packaging and textiles.
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.
The influence of road vehicle tyre wear on microplastics in a high-traffic university for sustainable transportation
Researchers examined microplastic pollution from tire wear in a high-traffic university environment. The study found that microplastic concentrations correlated with traffic patterns, peaking on weekdays and declining on weekends, with irregularly shaped black particles composed primarily of polyethylene, polypropylene, and polybutadiene dominating the samples, along with metal contaminants concentrated near the main entrance.
Comparison of traffic-related micro- and nanoplastic concentrations at three urban locations
Researchers measured airborne tire and road wear particles (microplastics shed from vehicle tires) at a busy urban road, a highway, and a park, finding rubber particle concentrations were 2-5 times higher near traffic compared to the park, with levels closely tracking other traffic pollutants like black carbon.
Mitigation of Suspendable Road Dust in a Subpolar, Oceanic Climate
Tire and road wear particles (TRWP), a major source of microplastics in waterways, are especially abundant in cold climates where studded tires are common. This study assessed road dust generation and found that traffic volume and road surface conditions are key drivers of TRWP pollution.
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.

Tire Wear Monitoring Approach for Hotspot Identification in Road Deposited Sediments from a Metropolitan City in Germany
Researchers developed a systematic road-sampling approach to identify urban hotspots for tire-and-road wear particles (TRWP) — a major category of microplastic pollution — by sweeping road-deposited sediments at six inner-city monitoring sites. Curves and traffic-light zones accumulated 8x and 3x more styrene-butadiene rubber (a TRWP marker) than straight road sections, respectively. Since tire wear is one of the largest sources of microplastics entering waterways via road runoff, this hotspot mapping method can inform targeted mitigation measures.
