Michelin Collection TRX ( 210/55 R390 91V )

The first 'low profile' tyre The invention of the TRX by Michelin in 1975 permitted a more even distribution of tension in the whole tyre casing, which is where the name of TR standing for “Tension Repartie” ('distributed tension') comes from. The TRX won renown in Formula 1 racing with Renault and Prost and in the world rally championship on the Audi Quattro, 205 Turbo 16 and R5 Turbo. For the first time, the tyre 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 tyre 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 tyre 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. • Remarkable grip thanks to the ideal distribution of pressure in the contact patch. • Excellent comfort due to increased useful flexing zone. • New look to the tyre/wheel assembly and the heavily sculpted tread pattern.
