Tires rubbing leafs

[Kitten7.3L]

I have a 2001 F350 SRW. Recently replaced worn front leafs with Rough Country 2.5" springs to level the truck. Leveled the truck perfect, added Bilstein HD's on front with the Cooper Discoverer ATR's 315/75/16 on 16"X7" stock wheels.

Do i need to lift the truck for the tires to clear the springs in a full turn? I plan on putting 16" X 9" after market wheels to better suit the tires. The will further complicate the rubbing issue if i am thinking correctly..... the 9" wheel will have a back spacing of 4.5"

My current 7" wheel has a back spacing of 3.5" so the 9" wheel will be 1" closer to the leafs?

I have checked the wheel clearance and measured that i will need the wheel to be negatively offset 1 inch.

Thoughts appreciated.

I have 16X10s with either a 4.25 or 4.5 back space on 315/75 BFGs. The ONLY time my tires contacted the leafs was when I was running 365s, as in 14.5 wide. If my 10s with a similar back space don't rub, 9s definitely won't.

I ran those same wheels with my 365/65-16 Toyos and they rubbed on the hanger/add-a-leaf front end AND the pro-Comp spring front end, Therefore, I really doubt that a lift spring would do anything about if the tires will rub.
