Soapy water or any other kind of lubricant won’t help in this case.

It’s flow rate you need, you can have lots of volume in a tank, but if there’s a valve or something limiting flow rate (as there probably is) then it’s going to struggle eventually. I actually reckon my old compressor was probably worse for seating than my Current ghetto Tubeless inflator. Urgh, I’m not looking forward to the prospect of another battle again tonight. Or maybe it’s time to experiment with deodorant and lighters (What could go wrong?). I must confess that despite seating countless tyres tubeless, I’ve never needed soapy water before so I guess that’s the next thing to try. However, I managed (not without difficulty) a Magic Mary in supposedly the same casing / width so I’m sure a Rock Razor must be possible. If you need 60 psi to get it to pop on then the combo is never going to work, give up now.

That thought had crossed my mind, I decided it was a bit wasteful, but my patience is wearing thin... I wondered if I could use an oversized tube with knots at each side that I could slip in and out (and thus get more than one use out of). If you dont mind sacrificing the tube, unseat a small section of tyre near the valve, cut the the tube and pull it out leaving the majority of the tyre seated. You have to be a bit careful but it’s not too hard – and arguably easier when the tyres are welded onto each side of the rim. I don’t think that I’ve ever managed to get the tube out by only unseating one side of the tyre. Release the pressure and then follow up immediately with the compressor. Compressor –> Coke bottle –> tyre is the best of both worlds of course. To be honest, if I could only have one tool, while the compressor makes life easier, I think the Coke bottle is probably more effective on stubborn tyres. The compressor is great for sustained air flow but it doesn’t give that short/sharp burst like the Coke bottle (and Airshot, I imagine). They’re just incredibly tight – which is a good thing if they are near the bead seat and just need a nudge but a bad thing if they need to slide a long way across the rim to get any form of seal. I had no trouble at all with the same tyres on a 25mm rim. I have the opposite experience of Super Gravity casings, they seat like a dream for me.
