We spoke to Vinson Bing, Director Norms & Regulations at Michelin China, ahead of his presentation at this November's Tomorrow's Tire Summit to get insights into what he'll be speaking about, why this research is important to the industry, challenges facing the industry, how Tomorrow's Tire can address them and more.
Your presentation is on Setting threshold of wet grip on worn tire, what can we expect to learn from your talk?
This recommendation is entirely due to the safety of the vehicle/tire operation. Globally, all relevant tire limits so far have been targeted at new tires, such as tire slip limit, rolling resistance limits, noise limits, and more. Then we should reflect on it: What are the initial principles we set these limits? Obviously, we want to ensure the safety, environmental protection and comfort of the tires at these limits. In this case, you should set a limit under the "worst condition" under the conditions under which the tire is allowed to use. Among the three key performances of the tire, the “worst condition” corresponding to rolling resistance and noise is the new tire; while the wet sliding performance is exactly the opposite, which corresponds to the later stage of tire wear, which corresponds precisely to the arrival of the tire to the legal wear limit ( The status of 1.6mm).
In short, if the wet skid performance of the tire is safe under the legal wear limit (1.6mm), then the tire is safe from new to old; otherwise, the wet slip limit is set for the new tire. Even if a new tire is satisfied, it is difficult to say whether it can meet the requirements of the slip limit after a period of wear.
Why is this research important to consumers and to the tire industry?
- Improve consumer driving/tire safety
- Improve the economics of consumer tires and make the best use of tires
- Contribute to environmental protection: On the one hand, it greatly reduces the production of tire solid waste, and on the other hand, it greatly reduces the CO2 generated by tire production activities.
- Promote technological innovation and progress in the tire industry
What are the main challenges that the industry is facing and how do you think that this conference can address them?
For the tire industry, I think the challenge comes mainly from：
- The rapid development and advancement of the automotive industry, of course, at the same time, we should also consider the challenges as opportunities, such as the development of electric vehicles and intelligent network vehicles.
- Increasingly stringent environmental requirements, such as the limited requirements for restricted substances in tires, and wastewater discharge requirements in the production process
- Standard and regulatory requirements for tire performance and grading are becoming more stringent
I believe that through the promotion of this conference, the industry will pay more attention and increase R&D investment appropriately in order to obtain better tire solutions.
What are you most looking forward to hearing about at Tomorrow’s Tire 2019?
Most want to hear about technological revolutions or innovations in the tire field, including innovations in traditional tire construction and formulation, including non-pneumatic tires, including new technology (RFID, TPMS, etc.) integrated into tire solutions, including tire testing technology New concepts and new achievements in terms of aspects.
