Best tubeless method i have ever seen

[Cyklon]

If you are a diver then do the following to seat tyre use a scuba cylinder and use a old cut LP pipe of the low pressure port of the demand valve, screw out valve and place over valve stem, open up and it pops it no sweat. I just unscrew a demandvalve and the hose fitting (Poseidon) fits over the tire valve. Just remember to hold tight.
