first off let me say "hello". new here and new to the jeep wrangler. My wife and i bought our first jeep (2000 TJ) a few months ago. I must say we fell in love and imagine we will always own one now.
I have always owned 4x4 vehicles but never had them lifted or put over size tires on them beyond maybe going from a 215 to a 235 but using the stock rims. Nothing drastic. This jeep came with stock rims (not a huge fan), a 2" lift and 31 x 10.5 R15 tires. We are happy with how it sits and dont have any intention of off roading in it. I imagine that's probably sacrilege to most jeep owners. But as some of you more experienced Jeep peeps may have already guessed...they rub on tight turns. I do not completely understand the whole back spacing and offset thing. i would like to fix that but I also want to change the rims. Ill put a link to the rims i am looking at and if possible let me know if these will work or if i need spacers.

thank you for any advice you can give
 
Those wheels have 3.75" backspacing. That will push the wheels out much further than the stock ones, and that should take care of any rubbing issues you have!

It's not sacrilege to drive a lifted Jeep and not off-road it. We all have different uses for our vehicles. The only thing that matters is that we all drive TJs!

Not for nothing but the only thing the rubbing does is hurt your feelings and since you have control of the steering wheel, just turn it back a smidge when you hear it rubbing.

Those are 15x8. With 31x10.5, is it possible to go with a wider wheel? Say 10"?

Also, you say you have a 2" lift...
It was my understanding that a 2" lift will clear 31's. I'm pretty sure mine is stock with the same tires and mine barely rubs. Only when I fully crank and hold the wheel. I've been using Mrblaine's method for the past year+ that I've owned it.
 
yeah it only rubs on tight turns so its not a daily issue but there are times when it comes into play. I'm not a fan of the rims so changing them is my plan anyway.
thanks for the replies

No, a 10" wide wheel is about 2" too wide for 10.5" wide tires. A 10.5" tire is only that width halfway up its sidewall which is a tire's widest point. The tire's mounting bead points are more like only 8" apart.

A 10.5" wide tire would have trouble remaining seated on a 10“ wide wheel, especially so if aired down for offroading.
