# Michelin Collection XWX – Iconic Performance from a Bygone Era ## Legendary Radial Technology for High-Speed Excellence The Michelin Collection XWX stands as a milestone in tire engineering, developed to meet the demands of the world’s fastest vehicles in the 1970s. Designed for sustained speeds up to 300 kph (186 mph), this radial tire delivered unmatched road holding, grip, and stability when high-performance motoring was entering a new frontier. Its flexible carcass and innovative internal structure provided exceptional comfort even at extreme velocities, making it the preferred choice for Europe’s most celebrated grand tourers and sports cars. ## Built for the Pioneers of Speed During the late 1960s and 1970s, unrestricted motorways in Germany and Italy became the natural habitat for high-speed driving. The XWX was engineered for this environment, equipping iconic models like the Ferrari 365, Lamborghini Miura, Porsche 911 Carrera RS, and Jaguar E-Type V12. Despite narrower tread widths compared to modern standards, the XWX achieved remarkable performance, proving that cutting-edge construction and materials could deliver safety, durability, and driving pleasure in equal measure—setting the benchmark for future high-speed tires..
