about to buy some rock crawler rims

I've been eyeing the black rock crawler rims for some time now. with 4wheelparts.com offereing free shipping, nows my time.

My question here...like most other relates to the back spacing.
I'm going to be putting on 31x10.5x15 BF Goodrich T/A KO on the rims and i was wonder which back spacing I should get for these

15x8" 5 on 4.5" w/ 3.75" backspacing


15x8" 5 on 4.5" w/4.5" backspacing

These are going to be put on a Daily driver 98 sahara i thought i would get some opinions before going ahead and ordering these rims

So any thoughts appreciated!!!

I would run the 4.5 BS. I currently run 31x10.5x15's with the stock Gambler 5.5 BS. It rubs at full turn (haven't bothered adding the washers yet). I do think that at 3.75 you'll stick out kind of far, and 4.5 would be plenty to avoid rubbing. As far as upgrades go, I just got my Spidertrax 1.25 spacers in the mail today, and this will bring me to 4.25 overall BS with the stock rims. 33's go on soon. I suspect I'll have to add washers to the steering stops to prevent all rubbing with a 12.5 wide tire, but all the 3.75 BS wheels I see stick out too far IMHO.

Actually, I'm running 32x11.50s on 15x8 Rock Crawlers with 4.5" of BS now.

In fact, I know a couple of guys running 35x12.50s with the same wheels and without any problems. Sure, at that size you'll have to add one or two washers to your steer stops to prevent rubbing of your lower control arms at a full turn but that's it. The biggest benefit to going with 4.5 BS is that more of your tire will stay under your fenders (in the case of a 31x10.50 - most all of it). This is very important especially if you live in a state that has fender laws like most do.
