I’ve just stripped my tubeless tyres off my wheels and replaced the valves and I’m now trying to get things back together. I’ve got an Airshot to do the pressure dump and one wheel worked fine, it took a couple of goes, but then the tyre locked into place and all was good, the second one just isn’t playing.
I do the air dump into it and it inflates, does the appropriate pops and seats nicely, no leaks at all, but when I let the air out so I can remove the Airshock, once the pressure drops to about 10 psi there is a big pop and almost all the tyre unseats itself.
I’ve tried at least six times, sometimes letting all the air out at once, sometimes just cracking the seal on the valve and letting it leak out over 10 minutes, it doesn’t matter, every time the tyre jumps off.
I’ve not put any sealant in yet as the majority of videos I’ve seen suggest adding it last, and I didn’t need it with the first wheel.
When I deflated them earlier, the tyres stayed where they were and I had to work to get then off.
In case it matters, the wheels are Bontranger Paradigm and the tyre a Continental GP5000.
Anyone any suggestions on what to try or what could be going wrong?
