It is so easy....even a caveman could do it!
First pull the rim off the wood wheel fetlo, let the air out of the tire, break the bead from the collapsable rim on both sides of the tire, I use a long handle tire tool, the one that also has a lug nut wrench on the handle end, and a short tire tool or long screw driver to hold the bead open as you go around the tire. Now mount the rim spreader (that one on eBay is just what you need for a car, it may work on a truck), next remove the cotter key from the latch or rotate the tab to release the rim latch, now use the rim tool to collapse the rim JUST enough to remove the rim from the tube and casing. Too much collapseing could ruin the rim, repair the hole in the tube or replace the tube, the inner flap and the casing centering the valve stem in the hole, carefully use the rim tool to spread the rim, watching the valve stem, and latch the rim together. Air it up and put it back on the wheel fetlo. Caution! Be very sure to get it on the rim correctly. If it is correct the rim bolts and valve stem will be in the right place, if wrong it can be heck to get back off, ask me how I know!
