You are talking about a tire with a bead to hold the sidewall of the tire in place. What David is working with is what I call a .5" tire. All .5" rims that I have seen (16.5,17.5,19.5,22.5,24.5, etc.) have a tapered bead and the pressure of the air inside holds the tire on the rim. If the tire looses air pressure the tire slides off the rim unlike a rim with a flat bead on it. What this does is protect the side wall of the tire from getting destroyed if the tire goes flat.Confused about the tractor tire. Was it punctured or did it just roll off the rim then let the air out?
Based on the 60 or so tubeless tires I have mounted (mostly motorcycle, all much smaller than your front tractor tire) once the tire bead is in contact with the rim seat (not the lip you concentrated on) the trick is to put air in faster than it leaks to fully seat the bead against the lip (that is what people do igniting butane or propane). You kept fighting it with a hammer when the job was already 98% complete, just needed more air. But this is also the most dangerous time, stand behind the wheel where the wheel can roll away, not with the tire/wheel broadside. When the tire jumps the last bit to seat on the rim it goes "Bang!" Twice. Once for each side.
This tool is one of the easiest ways I know of seating the bead on these types of tires. You just fill it with air and hold the wedge between the rim and the tire and open the valve. There is no struggle.
