3.75 Inch Backspacing with 31x10.5R15 Wheels

Hey everyone, kind of new to all of this so please bear with me. I've recently installed a 2 inch lift to my 1998 Jeep Wrangler. Now it's time to upgrade the tires/rims and I have 31x10.5R15 tires in mind with 15x8 rims. The question I have is the backspacing. It is 3.75 inches and I was wondering if that was going to cause any major rubbing or will I be okay? Also, is that a good combination of tires/rims. Thanks for your time and if anyone runs a setup like this, pictures would be awesome!

Not first hand, but from reading this forum like it's the bible, I've learned that it depends on the specific lift. What kind of lift did you add?

It's a great tire/wheel setup. The backspacing should be perfect. I'm not a TJ guy, but that backspacing and tire size worked great on my YJ with a 2" lift.
92 YJ, 4.0, 5" BDS springs, 1" booms, 1" BL, 35x12.50x15 MTZ's, Ford 8.8 with LSD, 4.10 gears. It's never done though.

Yes, 3.75 is just fine, if you later switch to 12.5 tires you'll want to look at less backspacing or spacers, but you won't have any rubbing or turning radius issues with that set up.
There are a million ways to build a Jeep, pick one and do it - you bought a canvas, not a painting!
