In this month's episode I sit down with Anurag Warhadpande from Bridgestone Americas. This podcast explores the critical role of tribology in tire performance, highlighting how factors like traction, wear, and noise are influenced by the tire-road interaction. Anurag discusses the science behind tire friction, including the mu-slip curve and road texture effects, as well as how wear mechanisms align with Archard’s Wear Law. The conversation also delves into the evolving needs of tires for electric vehicles, the rise of smart tire technology, and sustainability efforts such as bio-based materials and recycling innovations. Looking ahead, we examine future opportunities in tire development, including AI and IoT advancements, while debunking common misconceptions about tires.
