Helpful Expert Reply:
When you install the Timbren Trailer Axles # A20RS545 you will end up having a distance of 4-7/8 inches from the hub face to the trailer frame. The rim width of the # TTWAS15B45BM is 5 inches. When you add an additional 1 for the lip of the wheel and then divide that by two you end up with 3 inches of backspacing.
I went out into our warehouse and grabbed a # AM32238B to measure from the mounting surface of the wheel to the furthest point out on the tire and it measured 3-13/16 inches so this setup would fit and work well for you.
