Michelin TRX Tyres

Michelins Breakthrough TRX Design of Tyres

The invention of the TRX by Michelin in 1973 was the first instance of tyre 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 tyre was also altered to suit this new TRX rim design and the result is a more gradual curvature of the trx tyre sidewall giving exceptional directional stability and 'on the limit' handling, whilst also allowing for a comfortable ride.

TRX and TDX Rims - Designed by Michelin

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

These Michelin TRX tyres 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.
