Thread: Internal bead locks

When I say they still worked, the main tyre did not deflate and you could drive out of where you were. In the first case where 1 tube had a hole I was driving back from the Cape on sealed then unsealed roads with around 20 psi in the tyre. All it meant was that the tyre was not held in with the inner tube at higher pressures as this pressure too would have been 20psi. The second one was when I got a puncture and in fixing tyre a bit of a rash was noticed on the tube so was replaced as a precautionary measure.

The added advantage of bushability is appealing with being able to change damaged tyres with no more than a spanner.

I had a look, very interesting, but also seem very expensive.
I wonder if anyone has used them?
