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.

An overview of the key topics related to the study of tire particles and their chemical leachates: From problems to solutions
Researchers reviewed the current state of knowledge on tyre wear particles — rubber fragments shed by vehicles that are a major source of microplastic pollution — identifying key gaps in emissions estimates, detection standards, and understanding of the toxic chemicals that leach from tyre rubber into the environment. The review calls for closer collaboration between scientists, regulators, and the tire industry to develop solutions that reduce the environmental and health impacts of tyre pollution.
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.
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.

Challenges in Quantifying Tire Wear Particle Emissions on an Outer Drum Test Bed
Researchers worked to develop reliable methods for measuring tire wear particle emissions on an outer drum test bed, a key challenge since tire wear is a major source of microplastics. They found that a degumming method using talcum powder increased wear rates to realistic levels but complicated particle measurements, requiring new techniques to distinguish tire particles from the powder. The study highlights the technical difficulties involved in accurately quantifying tire wear emissions for environmental assessment.
The need for environmental regulation of tires: Challenges and recommendations
Researchers analyzed global regulations affecting tires across their entire lifespan and found a significant gap: while many rules address tire chemicals, safety, and recycling, none specifically regulate tire wear particles (TWPs) — the microplastic-like fragments shed onto roads. The authors argue that TWPs represent a poorly controlled source of environmental contamination and call for new risk-based regulations targeting their emission and toxicity.
Detecting the Invisible: Analytical Advances and Regulatory Gaps in Tyre and Road Wear Particle Pollution
This research review reveals that tiny particles from car tires scraping against roads make up nearly 28% of all microplastic pollution worldwide, yet we barely understand or regulate this massive source of contamination. These tire particles contain rubber, metals, and other chemicals that spread through the air we breathe and water systems, but scientists still lack consistent methods to properly detect and measure them. The study highlights an urgent need for better testing methods and pollution policies to protect human health from this largely invisible but widespread form of microplastic exposure.
