stock backspacing on my 86

Hey guys, what is the stock backspacing on a wheel on an 86 CJ7? I read a few pages on how to measure it and I just want to double check cause I've never done it before.

Also, I need to widen my stance and I'm getting new rims.. is 2" on each side too much to move it out?

Thanks!


Mike

My CJ rims have the numbers stamped into the back side of them, maybe have a close look at the back side of the spare tire?

They did use different rims for different packages. My 86 chrome spoke laredo rims are 15x7, not sure of the backspace number, didn't need to remember it.

My rims fit perfect. My 33x9.5's fit perfectly even to my fender flares.

Hmm ok well I will tell you what I'm up to. I want to go up to 35s with 15" steel black rims. I also want to kick my wheels out a few inches on each side because with the 4.5" lift i'd like to widen my stance. So I had 2 questions.

What should my backspacing be in order to do that?

How wide of a rim should I be on for a 35" 12.5 15" tire?

And who might be a good company to call to get the rims from? I can't seem to find somewhere that has a rim to match my criteria.

8" rim. 10" rims are not required until you get up into a 14.5" wide tire. Using them on a 12.5" results in a weaker bead, exposes the bead to more debris and obstacles, causes odd wear, and IMO looks stupid.

Being that you have a WT, backspacing about 4". I wouldn't go lower than that.

This is how NAXJA Midwest Chapter elected officials like to treat their resident users and former multi-year supporters.
