Do you have a charge pump or air compressor ? This is the one I bought. It works well. I have been able to seat 50+ tubeless tires on 6 set of rims.
But for some reason my lightbicycle wheelset and Vittoria Corsa G2.0 700x28 I had to do the trick posted by veloz where half seat tire on one bead, then do the same for the other side. then blast it air. Some tires I can seat with no sealant and add the sealant after the tire is seated. Other tires requires that I have to put in the sealant first to help the tires.
While I like my charge pump just fine I would have much preferred a small quiet air compressor. If you have the space for it I would highly recommend that instead.
