ClearOccurrence of tire-derived microplastics (TMPs) focusing on driving behavior
Researchers analyzed tire-derived microplastics (tiny rubber particles shed from vehicle tires) on roadways and found their abundance increased with traffic volume and was further boosted by hard braking — with aggressive braking increasing particle counts by about 28%. These tire particles are a major source of microplastic contamination entering waterways from roads.
Characteristics of Vehicle Tire and Road Wear Particles’ Size Distribution and Influencing Factors Examined via Laboratory Test
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.
Impact of vehicle type, tyre feature and driving behaviour on tyre wear under real-world driving conditions
Researchers measured real-world tire wear from 76 taxi cars over 22 months, finding that hybrid vehicles produced more tire wear than conventional cars, likely due to their heavier battery weight. Winter tires generated about three times more wear than summer tires, and front tires wore 1.7 times faster than rear tires. The study provides practical data on tire-derived microplastic emissions under actual driving conditions, which is important for understanding this significant but understudied source of environmental microplastics.

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.
Measurement and Analysis of Brake and Tyre Particle Emissions from Automotive Series Components for High-Load Driving Tests on a Wheel and Suspension Test Bed
This is not primarily about microplastics — it is a vehicle emissions study measuring brake and tyre particle emissions (size distribution, mass, and composition) under high-load driving conditions on a test bed, focused on aerosol characterization and non-exhaust emissions regulation.
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.
A comparative analysis of the chemical composition and biofilm formation on tire wear particles from six different tire types
Researchers compared the chemical composition and biofilm characteristics of tire wear particles collected from different vehicle types and road conditions, examining how these variables affect toxin and pathogen attachment. Tire wear particle composition varied with source, and surface properties influenced the attachment of microorganisms and contaminants, affecting their hazard potential.
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.

A dynamic material flow analysis model estimated the annual and cumulative release of rubber from vehicle tires into the environment via road wear, finding that tire rubber represents a substantial fraction of total microplastic pollution in terrestrial and aquatic systems. The study helps quantify this important but often overlooked microplastic source.
Analytical Investigation of Tire Induced Particle Emissions
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.
Comparison of traffic-related micro- and nanoplastic concentrations at three urban locations

The guide aims to help standardize how scientists study road dust microplastics, which primarily come from tire wear and plastic litter breakdown.
Proposed Index for Assigning an Environmental Label to Passenger Cars
This paper is not directly about microplastics; it proposes an improved environmental labeling index for passenger cars that adds tire wear and brake particle emissions to the current classification system, which only considers fuel type and vehicle age. While tire wear is a major source of microplastics, the paper's focus is on vehicle environmental scoring, not microplastic pollution outcomes.
