Design of an Instrumented Electric Vehicle for Tire and Road Wear Particle (TRWP) Sampling: a Focus on Representativeness
AI summary Read the abstract
Scientists built a specially equipped electric car to accurately measure tiny particles that come from tires wearing down on roads, not just car exhaust. As cars produce less tailpipe pollution, this tire dust is becoming a bigger source of air pollution and microplastics, so better measurement tools help researchers understand what we're actually breathing in.
As the contribution of exhaust emissions from road traffic to air pollution steadily decreases, non-exhaust emissions (NEEs), like tire and road wear particles (TRWP), have emerged as a relevant source of particulate matter (PM $$_{10}$$...

A Vehicle-Based Experimental Approach to the Collection and Characterization of Tire and Road Wear Particles
AI summary Read the abstract
Every time tires roll on the road, they shed tiny particles of rubber and mineral dust — some of the same "non-exhaust" pollution now raising concerns about microplastics in our air and environment. Researchers built a specialized vehicle system to capture and study these particles more accurately under controlled conditions, successfully recovering up to 81% of the worn tire material for close analysis. This matters because better collection methods are a key step toward understanding how much of this pollution we're actually breathing in or exposed to, even though this study focused on improving measurement tools rather than pinning down real-world health risks.
Analytical Investigation of Tire Induced Particle Emissions
AI summary Read the abstract
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.
Characterization of airborne tire particle emissions under realistic conditions on the chassis dynamometer, on the test track, and on the road
AI summary Read the abstract
Researchers developed a new tire and road wear particle (TRWP) sampling system and characterized airborne emissions under real-world conditions on a chassis dynamometer, test track, and public road. Emissions showed a bimodal size distribution with dominant modes at ~10 nm and 270 nm, with SEM/EDS revealing two particle formation mechanisms and confirming tire rubber as a major source of ultrafine airborne particles.
Real-World Emission Dynamics of Tire and Road Wear Particles: Impacts of Micro-Driving Behaviors and Roadway Characteristics
AI summary Read the abstract
Tiny bits of rubber and road material fly off your tires every time you brake, turn, or speed up, and this study found that certain driving habits and road designs create more of this pollution than others. As electric vehicles (which are heavier) become more common, this tire dust could become a bigger source of breathable particle pollution than car exhaust, making smarter road design and driving habits matter more for air quality.
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.
