Michelin Reduces Tire Wear Particle Emissions
Michelin is actively researching and reducing the environmental impact of tire wear particles, developing new materials and advocating for regulatory changes.
Tire manufacturer Michelin has focused in recent years on reducing emissions of tire wear particles (TRWP). These particles are generated by friction between the tire and the road surface, and Michelin has for years studied their formation and environmental impact.
According to the company, international studies indicate that tire wear particles contribute minimally to air pollution, accounting for less than 1% of PM10 and under 0.3% of PM2.5. Their impact on soil and water, however, depends on the distance from emission zones to aquatic environments. A substance called 6PPD-Quinone, formed during tire wear, has been identified as toxic to certain marine species.
In 2022, Michelin launched a dedicated research program to find a substitute for 6PPD, a substance crucial for tire safety. The company leverages its material expertise to develop lighter and more durable tires, which results in reduced abrasion.
Michelin reports that particle emissions from its products decreased by 5% between 2015 and 2020. The German automobile club ADAC has recognized Michelin as a leader in reducing tire wear particle emissions, noting that Michelin tires emit 26% fewer particles than the average of competing premium tires.
