On-Road Vehicle Measurement of Tire Wear Particle Emissions and Approach for Emission Prediction
AI summary Read the abstract
An instrumented measurement vehicle was developed to quantify tire wear particle emissions under real-world on-road conditions, identifying key driving parameters such as speed, load, and cornering that govern emission rates. The study supports the development of emission factors and regulatory standards for non-exhaust tire-derived microplastic pollution.
ABSTRACT Airborne particulate matter has long been associated with negative environmental and health impacts. Tire wear, in the form of particulate matter and microplastics, also poses a potential hazard to human health and the ecosystem. In order to develop measures minimizing tire related pollution, it is necessary to identify and classify all relevant influencing parameters. Within the scope of this study, a measurement vehicle is presented enabling sampling and measurement of tire-induced particles under varying operating conditions. The measurement setup ensures the separation of brake and tire wear and includes particle measurement devices as well as numerous vehicle motion sensors. Based on on-road tests, correlations between driving dynamic parameters and particle emission were analyzed. Furthermore, a first approach for tire-induced particle emission prediction is presented.

AI summary Read the abstract
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.
