Michelin Super Confort Stop S: Design & History
Michelin with it's Confort Cord tires had worked on developing crossply tyres that could run at lower pressures than the vintage beaded edge tires. The Super Confort (or Superconfort) that Michelin developed in 1932 gave the ability to run tires at a pressure as low as 22psi (1-5 bar). This lower pressure improved the longevity and comfort of the tire as the tire's name suggests.
Michelins next major innovation they implemented to these tyres came in 1935 with the thin zig zag cuts in the tires tread pattern. These are called sipes, they act by channelling heat into small "corrals" that let air flow between them, creating a natural heat dispersion and cooling the tire. They dramatically improved the performance of the tires in the wet.
At Borrani we suggest that while running Michelins Super Confort Stop tires to run at a pressure closer to 30 psi (2 bar) because the modern tarmac roads that we drive on today allow for higher speeds to be maintained for longer than was possible back in the vintage days.
