What is the least amount of back spacing for a 12.5" wide tire?

I'm going thru the same thing and this is what I came up with

Stock rim 7.5" wide with 6.25 BS and 10" tire and I have half an inch at full turn. So the tire is 2.5" wider than the rim so it will stick 1.25" out both sides. Thus BS to the edge of the stock tire is 7.5".

6.25+1.25=7.5

8" rim with 12.5" tire and 5" BS = 5" + 2.25" = 7.25" or a 1/4" more space to the sway bar than stock

9" rim with 12.5' tire and 5.5" BS = 5.5" + 1.75" = 7.25"

10" rim with 12.5" tire and 6"BS = 6" + 1.25" = 7.25"

Can anyone confirm my logic?:confused:
