1) If I purchase a 9" wide rim with 3.75 backspacing. Will it have a deeper dish than an 8" rim with 3.75 backspacing? By "deeper dish" I mean the outside of the rim will be deeper. 3.75 is the fixed depth of the inside of the rim right? SO an additional inch of width would protrude out the front right? The tires I'm looking at take an 8-9" rim. And I prefer the deeper dish look. So I thought I should by the 9" vs the 8".

2) If I purchase rims with 3.75 backspacing on a stock TJ, I should be able to ditch my spacers right? (I'm currently running JK rims with 2" spacers/adapters. I know the new wheels will have the correct bolt pattern. Just making sure it won't rub with 3.75" backspacing.)

1. Yes.

2. Yes. But whether or not there will be rubbing depends on many factors.
