I'm no expert (and we have some here) but there is difference in split-rim and split-ring wheels. Ag shops in my part of the world work on split-ring wheels all the time. I have the original wheels for my '51, 3600 which have the split retaining ring safely stored away. The only reason I changed to newer wheels is concern that while traveling, a shop with only younger employees would think the truck had split rim wheels and refuse to fix a flat. Most folks these days make that mistake.
