重要的事实

速度每降低 10 公里/小时，轮胎磨损粉尘 (TRWP) 就会减少 13-30%。
全球排放了 590 万吨轮胎磨损粉尘。

轮胎製造商面临的最大挑战之一是轮胎磨损粉尘 (TRWP)（一种微塑胶）的永续性问题。目前还没有关于 TRWP 的规定，但 Euro 7 将有一个新的标准，根据每公里 1 吨负载产生的重量来规范 TRWP。

本报告审查和分析了轮胎磨损法规，研究了轮胎製造商面临的技术和法规挑战以及他们正在采取的 TRWP 措施。特别是，我们正在调查 Euro7 标准和限制 6PPD 的美国立法中包含的新轮胎磨损测试义务的长期影响。

Key facts:

There is a 13-30% reduction in tire roadwear particles (TRWP) for every 10 km/hr speed reduction
5.9 million tonnes of tire roadwear particle emissions are generated globally

One of the biggest challenges facing tire manufacturers is the sustainability issue of tire roadwear particles (TRWP), a subset of microplastics. There are currently no regulations regarding TRWP, but Euro 7 will have new standards that will regulate TRWP based on the weight generated per kilometre per ton of load. This report examines the relationship between the size of the TRWP, the particle size distribution and tire materials, tire construction, road conditions, road type and other considerations.

With rising pressure to minimise tire particulate emissions, this expert study examines the technical and regulatory challenges facing tire makers and the steps they are taking to combat TRWP. In particular, it explores the long-term impacts of new tire wear testing obligations contained in the Euro 7 standard, and US legislation restricting 6PPD. Smithers analysis explores the tire material sets and construction innovations that can be used to improve tread durability, while maintaining performance and managing the transition to more sustainable transportation.

Key questions:

What steps are tire manufacturers taking to improve wear and reduce the environmental burden of TRWP?
What role do automakers and government play in developing an overall solution?
What are the technical challenges of mitigating tire wear particles under proposed regulations?
What are the key opportunities in sustainable transportation?

This report benefits:

Tire makers and producers of tire materials
Equipment suppliers to the tire industry
Participants in the tire markets value chain
