37x13.5 on 6" lift wheel offset question

[hoosiers16]

I plan on changing out my wheels soon, my current setup is 20x10 Fuel Hostages with little offset wrapped in 37x13.5 Nittos. As the title states I have a 6 inch Pro Comp lift. Just wondering what the max offset I could fit (trying to go for as a wide stance as possible)? For instance I'm looking at a set of 20x12 with -44 offset, would that "fit"? If not, what sort of adjustments would be required to make this setup work?

P.S. My current setup has no rub at full lock even on an incline, only adjustment made was removing the stock mud flaps

The extra wide stance is gonna cost ya more than the price of new wheels. Check your other thread. Some folks wouldn't necessarily call it an adjustment. Same wheels dims you are talking about and both Mikey and I went up to 8" inches of lift to outrun the rubbing. Does you lift have the Procomp radius arms? If so Procomp recommends minimum 4.5 inch back spacing to clear their radius arms at full steering lock.
