What Happened
Bridgestone Corporation announced the development of the industry's first Tire and Road Wear Particles (TRWP) vehicle collection method for truck and bus tires. TRWP are created by friction between tires and road surfaces and consist of tread and pavement materials. The new method builds on a similar system for passenger car tires introduced in 2025, aiming to deepen understanding of TRWP's environmental impact and promote reduction initiatives.

Bridgestone develops TRWP vehicle collection method for truck and bus tires.
The new method was presented at Tire Technology Expo 2026 in Hannover, Germany.
- Proving ground was thoroughly cleaned to prevent contamination from other particles.
- Suction devices and inlets compatible with large tires were developed, with a robust aluminum frame to withstand strong wind.
- After driving, TRWP remaining on the course and inside the tire cover were collected.
Why this matters
This new method accelerates research on TRWP, which are generated from tire-road friction, and helps Bridgestone develop strategies to reduce and minimize these particles, potentially lowering their environmental impact.
