Rim back spacing

So there's probably alot of threads about this, however I'm new to JF and would like to get my 25 posts in so I can do a build thread with pics , so just asking myself is kinda a win win right now I'm running a 96 Cherokee xj with 3" RC lift an 31x10x15s, their stock rims but not original to my jeep( they just look too clean to be.) so I'm assuming their stock 5.25 backspacing, the tires barely rub the LCA's, my question is I'm looking at Mickey Thompson classic 3 rims in satin black, I want to keep 31s an the 10x15 rim size but they only come in 3 5/8 backspacing, with 3 5/8" backspacing and 31s will they rub more or less than my stock rims with 5.25? Also what are y'all's opinions on 8x15s vs 10x15s still using 31s? Would that help or? Any info is appreciated an opinions are welcome

Personally I'd never run a 10" rim on a 31x10.5x15 , sidewalks r gonna b tapered out. Then again I prefer a 8-9" rim on 12.50 due to how they work when aired down.

I appreciate the response but I'm not sure I understand what your saying, it's a 15" rim by 10.50" wide tire an 31 " tire size, your saying an 8 " rim by 12.50" wide tire by X tire size right? I'm pretty sure a 12.50" wide tire is too wide in my case

He's saying he runs a 12.5 wide tire on a 15x8. You don't want to run a 10.5" tire on a 15x10, you don't get a good enough bead and you can't air down much. You want a 15x8.

What he is saying is a 10" wide wheel is too wide for a 10.5" wide tire. Especially since it's only 31" in diameter.

An 8" wide wheel would be the widest I would consider for a 10.5" wide tire.

Ahhhh, now I understand, i appreciate that guys, so now that it's clear my next rims need to be 15x8s to fit 31s better, would the 3 5/8 backspacing make them rub still or?

You will not rub on the LCA's but you may rub on the fender flares if you have any. I run 31/10.50/15 on a 15x8 rim with 4" BS at 4 inches of lift. Also if you are not bumpstopped you will hit you fenders with the tires when flexing since they will be sticking out much further than with stock rims. Not going to be able to stuff the tires into the fender like you could.
