Nice video. I changed my tractor tires last year (12x28) with the same reasoning. The "fun" part was emptying #400 of liquid ballast in each tire and trying to get the partially filled tube out. I had to do all this by gravity, no pumps. To break the bead I had to set a 6x6 post on the edge of the rim, put the weight of a vehicle on the post, and then use a #50 bar directed at the end of the post at the bead. I'm sure there is an easier way but it's what one has on hand.
Was it calcium chloride in the tires? That would be nasty. Not as bad as some tractor tires with powdered lead in them... enviro nightmare 101.
Workmaster, I jumped ahead in my thinking and thought you were going to put that post on the tire with a jack on it and put it under a cross beam and brake the bead.
