The Michelin XWX is a grand touring summer tire originally developed for legendary supercars of the 1970s, representing Michelin's classic tire technology designed for high-performance vehicles during an era when European motorways lacked speed limits. This vintage-specification tire carries VR and W speed ratings indicating capabilities from 131 mph up to approximately 170-186 mph, with construction specifically engineered to safely reach 300 km/h (186 mph) on period-correct supercars. Using modern materials manufactured to original specifications in small batches, the XWX is produced to preserve vehicles' authentic driving character alongside period-correct aesthetics essential for classic car authenticity and proper vehicle dynamics. The tire features flexible carcass construction combined with original internal design providing exceptional comfort when traveling at very high speeds, characteristics that made it the preferred choice for premium European performance vehicles.
The Michelin XWX is available in seven sizes within the 70-profile range, including fitments for iconic vehicles such as Porsche 911/924/944, BMW 730/733i, Mercedes 280/300/350/450 series, Ferrari Dino/208/308 models, Maserati Merak, early Lamborghini Countach, Jaguar, and Cadillac Seville among others. The 185/70VR15 size fits numerous Porsche and Maserati applications, while 205/70VR14 served as original equipment for multiple BMW, Mercedes, Ferrari, and Fiat models. This tire represents essential equipment for classic car enthusiasts, collectors, and vintage racing participants who demand period-correct specifications maintaining authentic vehicle performance characteristics and historical accuracy. Modern safety standards and rubber compounds ensure reliable performance while preserving the driving dynamics and aesthetic authenticity that original equipment tires provided to these legendary vehicles. The XWX serves owners committed to maintaining their classic performance cars with proper vintage-specification tires rather than compromising authenticity and vehicle dynamics with modern tire designs that alter suspension geometry, speedometer accuracy, and overall driving character of historically significant automobiles.
