The square inner tube:
- A square inner tube with bumps, the whole approach to the inner tube has just been rethought. For this, Michelin has implemented three technologies :
A bumpy design:
- Unlike a conventional inner tube that will react like a balloon that is punctured, it allows to reduce perforations.
- The combination of this characteristic with the prior injection of a self-sealing liquid effectively counteracts the horrors of perforation.
A square section:
- It provides optimum wedging on the rim while eliminating the phenomenon of twisting, which facilitates its installation.
