# Michelin Collection TRX B ## Revolutionary Low Profile Design Introduced in 1975, the Michelin TRX was the world's first low profile tyre system, marking a milestone in automotive engineering. By integrating the tyre and rim as a unified system, it delivered a breakthrough in performance and safety. The name 'TRX' originates from *Tension Répartie*, reflecting its core innovation: evenly distributed casing tension for enhanced structural integrity. ## Enhanced Performance and Safety The TRX system features a specially designed rim with a flatter, lower flange, enabling a smooth, continuous curvature of the tyre casing. This eliminates the traditional 'S' bend, improving responsiveness and cornering precision. Drivers benefit from superior grip, thanks to optimal pressure distribution across the contact area, and improved ride comfort due to an expanded flex zone. ## Iconic Heritage and Modern Appeal Famed for its success in Formula 1 with Renault and Alain Prost, as well as in rallying with legendary cars like the Audi Quattro and Peugeot 205 Turbo 16, the TRX remains a symbol of motorsport innovation. Its distinctive look, characterized by a sculpted tread and seamless wheel integration, offers both aesthetic appeal and functional performance for classic and vintage vehicles today.
