A systematic and comprehensive understanding of TRWP emissions requires detailed consideration of the mechanisms underlying particle generation. In this study, a design of experiment approach is applied to systematically investigate the influence from temperature, tire pressure and toe angle on the generation of airborne TRWP. By varying the parameters in a controlled environment on the chassis dyno with the DLR TRWP measurement method, the study isolates and quantifies their individual as well as interactive effects on emissions. The experimental design ensures statistical robustness while external factors remain controlled. First results demonstrate clear dependencies between the evaluated generation mechanisms and TRWP formation.

• Systematic analysis of influence – how different TRWP generation parameters individually and in combination influence emission levels
• Robust methodology – how a design of experiment approach ensures statistical significance and comparability of TRWP emissions
• Quantitative dependencies – which parameters show the strongest correlation to TRWP generation and how interaction effects can amplify or mitigate
• Framework for standardization – how this study contributes to defining boundary conditions for reproducible TRWP emissions testing
• Practical implications – how this study can help with test design optimization and benefit future testing procedures
