Any backspace, offset experts here??

[billjr]

I'm trying to figure out how to tell what new wheels will do to my 2022 wrangler rubicon. If I replace the stock rubicon wheels with wheels that have 0 offset, and 5" back space, essentially what do I end up with compared to what I have now? Will the new wheel (and tire of course) move in toward the frame or out away from the frame? So far with all the charts I can find I only get more confused especially because the offset and back space are both involved. That and my ignorance on this subject leaves me completely lost. I would appreciate any help anyone has to offer.

you will move out away from the frame... stock wheels have ~45 offset so you will move out with 0.. you will be poked out about 1 3/4"

Not trying to nitpick but for clarity it’s important to mention whether it’s positive or negative offset right?

yes negative offset gives even more poke.....oem wheels are 44.45 offset and 7.5" wide so ends up being just over 6" of offset.

The factory rubicon wheels are ~ +45mm offset is what I was leading to. I use on line offset to backspace calculators so I don’t have to think

Going from stock +44mm to 0 my 12.50’s tread went from ~even with the fenders to ~even with the added XR extensions.

Looking at that website and chart it appears 0 is 0 and has no positive or negative, correct?

Correct.

Thank guys, that link really helps me figure it all out, well mostly. I see how it shows where the wheel willl end up just not the exact measurements you guys seem to be able to do. I think maybe that's in the chart on the right. Anyway, I really appreciate all your help!!

Bill, thanks for your service! Keep in mind that the farther away you move your tires out away from the Jeep, with either wheel spacers or offset/backspace, you are increasing the scrub radius. Increasing the scrub radius puts more pressure on the wheel bearings, which may cause them to wear out sooner.

I have been using wheel spacers for tens of thousands of miles, and my OEM wheel bearings are still good - but I know I will have to replace them eventually, with better bearings, due to my increased scrub radius. They are relatively inexpensive to buy and replace.

Jeff, Thank you for your comment, I sincerely appreciate it still today!!..... That's kind of what I'm trying to do and why I'm here asking. I don't want to get to much "poke"? I guess it's called, not having my tires sticking out to far. I'm good with them just staying about the way they are which with my new tires is just a hair beyond the fenders and splash guards. Thank you again.

OK, now I see, it is on the right. This is a nice tool for someone like me. Can even calculate what they conclude is the proper tire pressure. Thank you all, I like this, probably because thanks all of you I can understand it.

You’re very welcome, sir.

For a very long time wheel spacers/adaptors have received a lot of negativity. Lots of advice how they are evil and will break whatever vehicle you put them on. You seem to have a positive experience with them. So, please help me out, how are they now OK?

quality spacers installed properly have always been fine...I have been using them since 2012 or so and never had an issue many 1000's of miles in all kinds of conditions...I only use Spidertrax or BORA's. follow the instructions and buy quality spacers and you won't have a problem, install them improperly and buy chinese made ones and all bets are off.
