Michelin TRX Tires and Michelin TDX Tires

The invention of the TRX by Michelin in 1973 was the first instance of tire and rim being designed to work together as a single unit. The new TRX rim was designed with a lower, flatter flange than that of conventional rims. The bead of the TRX tire was also altered to suit this new rim design and the result is a more gradual curvature of the tire sidewall giving exceptional directional stability and ‘on the limit’ handling, whilst also allowing for a comfortable ride.

Michelin also designed the TDX rim which again can only be fitted with a purpose built TDX tire. The TDX rim has two grooves running circumferentially around the bead seats and the tires have specially extended bead toes which are held in place by the grooves. The purpose of this is to prevent the tire leaving the rim thus giving the tire a limited ‘run-on’ capability allowing control of the car to be maintained in the event of a deflation, and a safe place to be reached for it to be changed.

These Michelin TRX tires and rims were standard fitment on many performance cars of the seventies, eighties and early nineties, such as Ferrari, BMW, Renault Alpine, Alfa Romeo, Peugeot and Renault 5 Turbo.
