Michelin Super Confort Stop S

Michelin; with it's Confort Cord tyres had worked on developing crossply tyres that could run at lower pressures than the vintage beaded edge tyres- The Super Confort (or Superconfort) that Michelin developed in 1932 gave the ability to run tyres at a pressure as low as 22psi (1-5 bar)- This low pressure improved longevity and comfort-
 
Michelins next major innovation came in 1935 with the thin zig zag cuts in the tyres tread pattern, called sipes- These dramatically improved the tyres performance in the wet- The clue is in the name Super Confort Stop S-
 
At Longstone we would recommend even while running Michelins Super Confort Stop S tyres to run at a pressure closer to 30 psi (2 bar) because the tarmac roads we drive on these days allow higher speeds to be maintained for longer than was possible back in vintage days-

Superconfort

Michelins development of the Superconfort tyre was a new technology- As a way of trying not to allow their new technology from being mixed up with the standard wheels that people were fitting in perod Michelin made the Bibendum rim which was millimetric- Today all the Michelin SCSS (Super Confort Stop S) vintage tyres are manufactured for fitment to 40cm/400mm rims- You cannot fit a 40cm tyre onto an 16" rim any more than you can fit a 16" tyre onto a 400mm rim-
