# Michelin Collection XWX – Legendary Performance for Iconic Supercars Born in the golden era of high-speed motoring, the Michelin XWX was the definitive radial tyre for the world’s fastest cars of the 1970s. Engineered to handle speeds up to 270 kph (168 mph), it delivered exceptional road holding, remarkable grip, and superior comfort at high velocities—thanks to its flexible carcass and innovative internal structure. As a VR-rated tyre, the XWX was built for sustained performance above 210 kph (130 mph), making it the preferred choice for legendary vehicles like the Lamborghini Miura, Ferrari 365, Porsche 911 Carrera RS, and Jaguar E-Type. Despite narrower widths compared to modern standards, the XWX mastered the balance of safety, speed, and driving pleasure. Why was the XWX so groundbreaking? It combined radial durability with high-speed capability at a time when few tyres could. What made it ideal for classic supercars? Its refined construction delivered stability and comfort even on unrestricted autobahns.
