With the single nut at the bottom of the carrier removed, there should be an angled steel piece located under where the removed nut was, remove it. Now grasp the tire/split rim assembly with both hands at the lower end of the assembly and pull rearward until the tire/rim is beyond the tire carrier. Now lift the tire/rim assembly vertically up and out of the carrier until the valve stem exits the hole in the tire carrier. The tire/rim should be free at this point.
I'm old but not a pro and I doubt that bibbed overalls will help but if you get them and wear them you'll probably look cool and put a smile on the neighbors.
