I've used these only a few weeks. OEM on RM Flatline Park. Fixing flats and changing tires is a real pain in the ass. Once seated, the tires are not very likely to slip on the rim. But to break the bead, I had to pinch the tire in a vice and rock the wheel latterly. I don't recommend this as you can damage the tire, rim or yourself. If you can find a better way, do so.

The rims do seem durable. Any tire with wire bead will require a lot of work and heavy-duty tire irons.
