What are TRWP and how are they generated?
Tires play a unique role in providing safe mobility, as they are the only connection between the vehicle and the road. The friction between tires and the road surface, which is critical to vehicle safety and performance, causes abrasion and creates tire and road wear particles (TRWP). They are approximately half-and-half mixture of tire tread and road pavement material.
TRWP generation is influenced by many factors impacting tire wear, including tire design, vehicle characteristics (such as weight, distribution of load, location of driving wheels and suspension types), road surface (material, runoff design, roughness), weather (humid or dry, hot or cold), road topology (hilly or flat, winding or straight), and driving behavior (aggressive or smooth driving, high or moderate speed, respecting the correct inflation pressure, braking).
