My 1959 3800 (1 ton) with dual rear wheels had 18" sectional wheels with an oddball removable bead ring. It was a full circle ring with two relieved areas that could be pried up over the main wheel piece and slipped off sideways after the tire was deflated and the bead driven down with a duckbill tire hammer. The rings were very susceptible to rust damage and had to be inspected carefully and wire-brushed at each tire change. The locking lip was extremely narrow.
