ZX

The “X” evolution

Radial technology

The benefits of the radial tyre compared with the standard tyre were visible in all areas:

- greater safety (enhanced road-holding, more grip, shorter braking distances).

- economical to use (significantly increase mileage and reduced fuel consumption).

- increased comfort thanks to sidewall flexibility.

In the 1950s, the superiority of the X tyre was such that it was fitted by a numbers of racing drivers, althrough Michelin was not officially involved in car racing at this time.

1968 was the year of ZX development, with even more sipes offering better traction and stability in all weather conditions.
