I had fun lastnight trying to get the old tires off. I took a reciprocating saw with a hack saw blade to one tire and cut around the sidewall on each side. I then took a couple crow bars and removed the cutoff. I then took some snips to cut off the rim flap. Interesting that I could cut the rim flap with snips but the tube would not cut. I then tried taking the saw to cut off the rest of the tire but the beads were still stuck on the rim and I couldn't get a good angle to get the tire fully cut off. I looked around wondering what I could use to get the beads unseated. Finally looked at the tractor with a loader. I pulled out the wheel with the intact tire since I thought I was going to have problems pushing on the little flap left on the tire I cut off. I took what I think is an old tractor or implement weight and put it on one side of the rim and pushed down with the front edge of the loader on the tire on the opposite side. I worked my way around both sides and it looked like it loosened the tire from the rim. I then tried the one where I had cut off the tire. That actually worked very easily and the leftover ring of tire slipped off into the well. Then I cut off the other tire and noticed all the previous work was no good since the rim flap wouldn't let the tire fall into the well so out came the tractor again. I did finally cut through the bead with the saw on one wheel, that was a lot of work just to do that. I then gently took my small sledge and knocked the rust off the inside of the rim next to the ring. I will try to take some pictures tonight. I am having a bad feeling now looking inside the rims. I will try to get the ring loose and cleaned up. I did find a truck tire place in town that will work on split rims. Once I get them cleaned up I will be taking the rims to them to see what they say and if all is OK I will have them mount the tires. I have no desire to try mounting these myself.
