Double Rivet

An iconic tread pattern

Conventional or cross-ply or bias tyres replaced beaded edge tyres and made up the second generation of detachable tyres.

They benefited from two major innovations:

The emergence of carbon black and textile cords in tyre carcasses.

The introduction of carbon black in 1917 led to a five-fold increase in tyre service life.

The insertion of layers of textile cords parallel with each other in tyre carcasses gave rise to the so-called “câblé” tyre in 1919, then “câblé confort” in 1923, which was the first low pressure car tyre (2.5 bars).

"Double Rivet" is in fact the name of a tread pattern reminiscent of this assembly component which emerged with the first generation of beaded edge tyres. This distinct tread pattern was retained for the first tyres with bead wires in 1925. It is still available in the fourteen sizes of the Michelin Collection range, thus enabling enthusiasts to fit numerous pre-war vehicles.

Of course, materials used in the 21 st century to produce these tyres stem from current technology. These tyres must thus be inflated in compliance with the pressure load scale available on page 5 of our technical catalogue. It will be determined by the weight supported by each tyre, for optimum road holding and high durability.
