Rethinking Tire Wear Particle Collection: Why Simplified Laboratory Studies Are Essential for Emission Reduction

Original language description

Reducing emissions from tire and road wear particles (TRWPs) is a growing priority in thecontext of environmental protection and sustainable mobility. A major challenge lies in the collectionand analysis of these particles, particularly those generated in real-world driving conditions directlybehind the tire. While promising concepts for on-road particle capture exist, practical implementationremains technically demanding and scientifically uncertain due to factors such as turbulent airflow,surface adhesion, and rapid particle dispersion.In this study, we explore an alternative strategy focused on simplified laboratory based investigations.Rather than attempting to replicate real-world tire abrasion, we use the DIN abrasion test (ISO 4649)as a baseline method. Its role is not to simulate actual tire road interaction, but to offer a widelyaccessible and standardized means of generating and analyzing wear particles under controlledconditions. This approach enables consistent evaluation of how different material parameters andmechanical responses influence wear particle formation and recovery rates.Preliminary observations indicate that even under ideal lab conditions, full recovery of rubber abrasionparticles (rAPs) remains difficult, due to factors such as particle adhesion, secondary dispersion, andhandling losses. If complete particle capture cannot be assured in such a controlled setting, this raisesquestions about the feasibility of achieving reliable real-time collection behind a moving wheel underfar more complex, dynamic conditions.We argue that laboratory studies, even those based on simplified test methods, are indispensable forunderstanding the fundamental mechanisms that lead to particle formation. This understanding is aprerequisite for designing tire materials and structures that minimize emissions at the source.Ultimately, progress in reducing TRWP emissions depends not only on engineering better collectionmethods, but on rethinking abrasion as a material driven process that must first be understood in detailbefore it can be managed in practice.
