ClearMarkovian city-scale modelling and mitigation of micro-particles from tires
This modeling study estimated tire wear particle emissions at a city scale, finding that as vehicle fleets electrify and tailpipe emissions decline, non-exhaust emissions from tire and brake wear will become the dominant form of traffic-related particulate pollution. Because tire wear particles contain microplastics and toxic chemicals, this shift raises serious public health concerns that warrant stronger regulatory attention.

Tire Wear and Pollutants: An Overview of Research
This review provides an overview of tire road and wear particles as a major source of microplastic emissions, examining both experimental and mathematical approaches to measuring tire wear. The study notes that while tire wear particles are found in alarming amounts across various environments, they remain less studied than other microplastics, and calls for more accurate simulation models to predict tire wear emissions.

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.
On-Road Vehicle Measurement of Tire Wear Particle Emissions and Approach for Emission Prediction
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.

Tyre-Induced Microplastics: An Unknown Arena for e-Mobility
This review examines tyre-induced microplastics as a major but underappreciated non-exhaust vehicle emission, particularly in the context of the transition to e-mobility, and evaluates how tyre abrasion contributes to traffic-related microplastic loading in the environment. The paper highlights that electric vehicles, despite eliminating exhaust emissions, may generate comparable or greater tyre wear particles due to higher vehicle mass, making tyre microplastics an urgent area for regulation.
Mechanism of microplastic and nanoplastic emission from tire wear
Scientists showed that normal tire wear produces two distinct populations of plastic particles: smaller airborne nanoplastics that stay suspended in the air, and larger microplastics that settle to the ground. Nanoplastic emissions increase dramatically with vehicle speed and weight, and electric charge keeps the smallest particles floating in the air where they can be inhaled. This research identifies tire wear as a major and previously underappreciated source of breathable nanoplastic pollution.
Contribution of Road Vehicle Tyre Wear to Microplastics and Ambient Air Pollution
This review finds that tire wear from road vehicles contributes one-third to one-half of all microplastics released unintentionally into the environment, with passenger cars generating about 110 milligrams per kilometer driven. Most tire particles end up in soil, but a portion becomes airborne, contributing 5-30% of road transport particulate matter emissions. Since the smallest tire particles can be inhaled, this is a significant and often overlooked source of daily microplastic exposure for people living near roads.
