MICHELIN Tyres of the 1930s

Cross-ply tyres with bead wires.

Cross-ply Tyres with Bead Wires

Replacing beaded edge tyres, cross-ply tyres with bead wires formed the second generation of detachable tyres. These tyres benefited from two major innovations: the introduction of carbon black and the appearance of textile wire cords in the tyre carcass.

Increased Service Life

The incorporation of wires into the bead in 1925 led to an improvement in tyre retention on the rim. These tyres also benefited from two major innovations prior to their creation:

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

- the appearance of layers of textile wire cords parallel with each other in the tyre’s carcass, which gave rise to the so-called "cablé" tyre in 1919 and the "cablé confort" in 1923, the first low pressure car tyre (2.5 bars 36 psi).

In the category of cross-ply tyres with bead wires, we currently market two products:

Double Rivet

"Double rivet" is in fact the name of a tread pattern which first saw the light of day with the first generation of tyres for motor cars, beaded edge tyres. This tread pattern was retained for first tyres with bead wires in 1925. This tread pattern, with its old-fashioned appearance, was truly revolutionary at the time. It was also the inspiration for the first radial tyres.

Supercomfort

Resulting from research which led to even lower pressures and slower wear, Michelin brought out a very low pressure tyre in 1932, the "Superconfort". 1935 saw the launch of the “Superconfort Stop S” the first tyre with a heavily siped tread pattern, specially designed for wet surfaces. At the time, Michelin was the only manufacturer who knew how to make this type of tyre with the famous wavy "zigzag" sipes, which greatly improve safety because of the excellent grip they give. As its name suggests, the "Superconfort Stop S" tyre offers exceptional comfort, in addition to its performance on the road.
