BF Goodrich TRX tires have remarkable grip thanks to the ideal distribution of pressure in the contact patch with excellent comfort due to increased useful flexing zone. TRX tires are built in authentic molds and are available in sizes for European and US vehicles. The invention of the TRX tires by Michelin in 1975 produced more even distribution of tension in the whole tire casing, which is where the name of TR standing for “Tension Repartie” originates.The Michelin TRX gained acclaimed success in Formula 1 racing with Renault/ Prost and in the world rally championship with the Audi Quattro 205 Turbo 16 and Renault R5 Turbo. For the first time, the tire and its rim complemented one another perfectly, working as a single unit. The rim underwent a fundamental transformation, the essential characteristic of which was a flatter, lower flange. This new design of the rim and tire bead resulted in a gradual curvature of the casing, without the "S" shaped flexing inherent in traditional designs. Thanks to this innovative construction, the TRX tire offers better directional stability and makes a great contribution to the active safety of the vehicle, thanks to its exceptional handling close to the limit, especially when cornering.
