I've been running tubeless for a couple of years now and find it less hassle than messing about with a wobbly inner-tube.
However have recently acquired some American Classic tubeless wheels and unfortunately Schwalbe tires are too loose a fit to get any kind of initial seal.
Switched allegiance to Bontrager which go up with a few gentle pumps, no soap/water and even hold air without sealant for 24hrs - bliss!
Rashly bought another Schwalbe to try again (I'm a racer so a bit of a tire obsessive)but same issue.
Thought about adding a couple of layers of tape to the rim to build it up a bit.
If I have to resort to using a compressor, I guess I need an adapter to convert the Presta valve to Schrader. Is my local petrol station the best place to go?
Please no replies about soapy water etc. I've fitted a lot of tires in the last two years and know all the usual tricks.
