They'll fit on your factory rims just fine, sure... but they won't fit on your jeep with stock rims just fine unless you consider rubbing fine.

Well mine rub now, and it's fine, but they rub Bcuz i got not enuff BS. What would a 31 on a fact wheel rub on with a 3" lift?

Im assuming it'd rub on LCA.

I would stay 3.75 or 4

It's not that you don't have enough back spacing, it's that you have too much backspacing. The less backspacing you have, the further out it moves the rim. Lift doesn't matter in that aspect, it's the lower control arms you're hitting.

O I see. Mine rubs the fender flares because i don't have enuff backspacing and the tire sets out too far. It rubs the lower rear corner of the flare when i turn.

Sawzall would take care of that in a hurry:icon_biggrin:

Yeah lol, but i was tryin to keep my front tires from slingin all the water and grit and grime all up in my door hinges, so insteada pullin the whole inner fender well i just trimmed it a lil. Slings everything in there anyway. I thought about fillin the fenders with GreatStuff but idk if that's a good idea...

Haha ya i need to fill mine in...i heard pool noodles work pretty good...just cut, paint, and stuff it up in there.

Idk lol, GreatStuff seems likea better idea than a pool noodle.

less backspacing will keep the wider tire away from the control arms.
a wider rim will put those same tires against the control arms.
get it?

If you want to retain water and speed up the rust.

What would you reccomend?

seal up all exposed metal and then stick some pool noodles in there... lol. Seriously, and spray in foam type stuff is going to retain moisture and cause rust. at least the pool noodles you can pull out to clean in there to prevent rust.

go with the pool noodle.

you can paint it whatever colour you like.
