I agree with you sweetk30, the lock ring wheels were considered safe by the industry and still being used in the 90's. I guess it boils down to economics, they require more skilled labor, which means more expensive to deal with vs. a solid rim which is simple and requires less skill. IMO, it was favored in heavy duty extreme work vs. flat highway hauling work. I understand all the advantages of the solid rims and radials, but, I'm beginning to miss the look of a heavy duty bias ply tire on a lock ring wheel, not only on big rigs, but on pre mid 70's 3/4 and 1 ton pickups.
