How do you make a split rim widow maker, out of a 3 piece, snap ring wheel. Sounds like that tire man of many years, has been misinformed.
I know, he informed me that ALL these multi piece rims are split rims and are dangerous. They won't work on the real split rims of course but will work on these AR type. That is kind of typical, know it all and you don't know nothing. I took a wheel off my junk parts truck and looked at it. Guess what? That one I think IS an RH-5, for sure is 2 piece and looks like the picture in the shop manual of the "optional" 2 piece rim. That old parts truck has another one I think on the front. I found a good AR type I got off another scrap truck in a SD junk yard several years ago. Took that back to the Cenex today and will have the good tire on the cracked rim put on it. Cleaning in prep for painting now, lot of dirty work.
