Default 31x10.5 with 3.75" backspacing?

i found a set of 31s on some black procomp rock crawler rims with a back spacing of 3.75". will this be alright for a 99 jimmy?

i know it wont clear stock but my shackles are in the mail and tbar crank will get done with shackle install

I doubt you'll be able to turn much unless you cut your fenders. I have 4" backspacing and couldn't turn the steering wheel more than about 15 degrees either direction without the tires hitting. After trimming, I don't have any problems.

Also, how wide are the wheels? 8" wide will push them out further and it might be harder to get them to fit well.

A body lift will help a lot.

I think it was about 2.5" measured from the bottom. I tried my best to blend it in with the curve of the wheel well. It turned out pretty well, I think. I notice it because I look at it a lot but I've never had anyone that I know ask me why there are some open holes at the bottom of my fenders. The pic on the bottom is from a couple weeks ago, 9+ months since I cut them and no rust at all.



Also, I just noticed in your pic, the holes for the lugnuts look like they're wearing out. One of our members posted a while back about some procomp wheels that were part of a bad batch or something and the lug nuts reamed out the holes and a wheel came off while driving. It's probably just the black finish that's come off but make sure you check them over real well before mounting them.

I need to take a pic of the trimming I did

cut a pie slice out of bottom and stitch welded it back so that I would have no holes and the liner would be attached

Yeah, this is the good way to do it. I started out that way and sort of messed up the sliver that I tried to leave so I just cut it all off.

I do understand how that is. if you ever try it on another vehicle and you mess up the sliver, just put a piece behind the cut and stitch it together
