The problem has resolved. A previous poster suggested trying a 26x1 3/8 tire on the new rim. Sure enough, too large. I measured the old rim I am replacing(clearly marked Araya 26x1 3/8) the outside diameter is 602mm, the smaller new rim measures 575mm. I was awake when I placed my order and I know what I selected. Never discount that vendors can make a mistake same as anyone.
