Development of Tire-Wear Particle Emission Measurements for Passenger Vehicles

Abstract In this study, we aimed to develop a new method for measuring tire-wear particles of less than 2.5 μm generated from vehicle use. We also devise evaluating the emission factor particles. To an evaluation particles, examined several factors, such as how tire components in airborne collected on sampling filter were measured, comparison obtained laboratory study and on-road using test vehicle, mass weighting balance. Measurements carried out measurement proposed herein. The amount wear that was almost constant speed range 20–40 km/h but influenced by change lateral acceleration 0–0.4G. Furthermore, relationship between force can be shown quadratic polynomial. estimated applying relational equation profile JC08 used Japanese exhaust gas tests. 3.7 mg/km-vehicle. ratio tread about 3.3% at PM 3.7% 10 .
