22'' on s-10

what is the correct backspacing for a 2gen s-10 with 22x8.5

I think its around a +18 give or take a couple but I might be wrong, its been known to happen before.

not sure if this helps, but i got 22x9 on the rear of mine and they are 5.5" backspacing. fit perfect.

the front is 20x8.5 with 5.4" backspacing. if i turn all the way, it hits the frame. not a big deal to me.

any one know hot to keep the a/c on 20's with a bodydrop and the how to with a bodydrop? any one want to bulid me one i will pay
