Tire Wear Particles: A Significant Source of Microplastic Pollution

Tire wear particles are a major contributor to microplastic pollution, posing significant environmental and health risks throughout the tire lifecycle.

The Science of The Total Environment · 2024

Key Findings

01Tire wear particles are a primary source of microplastics in urban runoff.
02Tires release a complex mixture of heavy metals, plastics, PAHs, and other toxic compounds.
03The production, use, and disposal of tires present significant environmental challenges with limited effective solutions.
04Recycling and post-wear uses of tires can also be sources of pollution.

Application

Design takeaway

Designers must account for the environmental burden of tire wear particles and chemical leachates, seeking materials and product lifecycles that minimize pollution.

How to apply

When designing vehicles or products that utilize tires, research and specify materials with lower wear rates and reduced toxicity. Investigate innovative recycling methods or alternative materials for tire components.

Project actions

01Investigate the wear characteristics of different tire materials.
02Research the chemical composition of tire components and their environmental impact.
03Explore sustainable alternatives for tire materials or end-of-life solutions.

Method & Evidence

AimTo synthesize current research on the environmental impacts of tire wear particles and their associated chemical cocktails across the tire lifecycle, identifying knowledge gaps and potential remediation strategies.

MethodLiterature Review and Synthesis

ProcedureThe authors reviewed and synthesized existing scientific literature and data concerning the environmental and human health risks associated with tire production, use, and disposal. They examined tire emissions as whole tires, particles, and chemical compounds, and discussed their transport pathways and toxicological effects.

ContextEnvironmental Science, Materials Science, Product Lifecycle Analysis

Variables

IVTire material composition, tire tread design, road surface conditions, environmental conditions (e.g., rainfall).

DVAmount of tire wear particles shed, chemical composition of leachates, microplastic concentration in runoff.

CVVehicle speed, braking/acceleration patterns, tire pressure, ambient temperature.

Strengths & Limitations

Strengths

+Comprehensive synthesis of a complex environmental issue.
+Holistic examination of the tire lifecycle.
+Identification of critical knowledge gaps.

Limitations

The complexity of tire wear particle composition and environmental transport can make direct testing challenging. Sourcing and testing various tire materials may be difficult.

Reliability & validity

The reliability of the findings depends on the quality and consistency of the synthesized research. Validity is supported by the broad scope of the review and the synthesis of multiple studies.

Think critically

How can designers mitigate the environmental impact of tire wear particles, and what are the economic and performance trade-offs associated with these solutions?

Design Principles

"Minimize the shedding of microparticles and the release of toxic chemicals throughout a product's lifecycle."

Understanding the environmental impact of tire wear is crucial for developing sustainable material choices and end-of-life strategies in product design. This research highlights the pervasive nature of tire-related pollutants, from production to disposal, urging designers to consider the full lifecycle implications of their material selections.

What This Means for Your Design

Tires wear down and release tiny plastic bits and chemicals that pollute our water and air, and it's hard to deal with old tires. Designers need to think about this pollution when making things.

How to use in your project

1.Use this research to justify the selection of specific materials for a design project, focusing on reduced environmental impact.
2.Incorporate the lifecycle assessment of tires into the evaluation of design alternatives.
