ClearA comparative analysis of the chemical composition and biofilm formation on tire wear particles from six different tire types
Researchers analyzed the chemical composition and biofilm communities forming on tire-wear particles compared to other microplastic types, finding that tire wear particles support distinct microbial assemblages. The unique surface chemistry of tire wear particles may promote the attachment of pathogens and toxin-producing microorganisms.
Investigation of physical and chemical properties of particulate matter caused by vehicle tire wear
Researchers characterized the physical and chemical properties of submicron tire wear particles generated from vehicle use on roadways. Using advanced analytical techniques, they identified the elemental composition and morphological structure of these particles, finding notable concentrations of metals and heavy metals. The study highlights that tire wear particles are a significant source of microplastic and chemical pollution with potential implications for human health and the environment.
Tire wear particles in different water environments: occurrence, behavior, and biological effects—a review and perspectives
This review examines tire wear particles, a major but often overlooked source of microplastics in water environments. Tire particles release toxic chemicals as they break down in water and can harm aquatic organisms, but most research has focused only on the chemical leachate rather than the particles themselves. Since tire wear contributes a large share of total microplastic pollution, understanding its full impact on water ecosystems and the food chain is important for human health.
Toxicity of tire wear particles and the leachates to microorganisms in marine sediments
Researchers investigated the toxicity of tire wear particles and their chemical leachates on bacteria in marine sediments. The study found that aged tire wear particles were more toxic than pristine ones, and that leachates were even more harmful than the particles themselves, with zinc identified as the primary toxicity-causing substance.
A study on the aquatic degradation of tire wear particles: Impact of environmental factors and material formulations
This study investigated how tire wear particles degrade in aquatic environments, examining the effects of environmental factors such as UV exposure and water chemistry on particle breakdown.

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.
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.
Priorities to inform research on tire particles and their chemical leachates: A collective perspective.
An international interdisciplinary network of researchers identified priority research areas for understanding the ecological impacts of tire particles and their chemical leachates — a rapidly growing area of concern given that tire wear particles are one of the largest sources of microplastics in urban runoff. The priorities span toxicology, exposure assessment, and regulatory relevance.
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.
Brand-Specific Toxicity of Tire Tread Particles Helps Identify the Determinants of Toxicity.
Researchers systematically evaluated the toxicity of tire tread particles (TPs) from different brands on soil model species at environmentally relevant concentrations, identifying specific chemical determinants responsible for varying degrees of soil fauna toxicity across brands.
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.
Tire wear particles: An emerging threat to soil health
This review synthesizes knowledge about tire wear particles — a major but often overlooked source of microplastic-like pollutants — in soil ecosystems. Tire wear particles contain toxic metals and organic compounds that harm soil microbes, invertebrates, and plants, but most research to date has focused on aquatic systems rather than soils.
Tire Wear Particles and Their Role in Microplastic Pollution
This review synthesized research on tire wear particles (TWPs) as a major but often overlooked source of microplastic pollution, contributing roughly six million tonnes annually. TWPs spread into soil, rivers, and oceans, where they carry toxic chemicals including heavy metals and PAHs, posing risks to wildlife and potentially entering the human food chain.
Tire wear particles: An emerging threat to soil health
This review examines tire wear particles as an emerging source of soil contamination, finding that these microplastics contain a complex mixture of rubber, metals, and organic chemicals that can harm soil organisms. Researchers highlight that most current studies focus on individual species, which may underestimate the cascading effects on entire soil ecosystems. The study warns that tire wear particles could alter essential soil processes and ecosystem services, representing a significant but underappreciated threat to soil health.

Methods for laboratory-generation and physico-chemical characterisation of tyre wear particles
Researchers developed a lab method to generate tire wear particles using a friction machine and then identified a suite of chemical compounds that could serve as reliable markers for detecting these particles in environmental samples. Tire wear is one of the largest single sources of microplastic pollution globally, yet quantifying it in the environment has been hampered by the lack of agreed marker compounds. This work lays groundwork for standardized monitoring of tire particle pollution in soils and waterways.
Risk assessment of tire wear in the environment – a literature review
This review assesses the environmental risks of tire wear emissions, which release microplastic-like particles containing polymers and potentially toxic chemicals into water and soil. While initial risk estimates suggest low risk from the particulate emissions themselves, the chemicals that leach from tire particles remain poorly characterized. The findings are relevant to human health because tire wear is one of the largest sources of microplastic pollution, and the leached chemicals may enter drinking water.
