Need help correct wheel size

[sixonthefloor]

Ok I'm sure this has been asked before and I did use the search but it kept giving me only 2 results that didn't help me at all.
My question is I'm looking into getting some new steel wheels for my 85 4runner. It has 6inches of lift. I'm gonna run 33s or possibly 35s x 12.5.

What width and back space will I need to get.

Thanks

I don't have an answer for you on the backspacing but if you go to the tire manufacturer's website, you can normally find the recommended rim width range for any particular tire. You can normally go a bit out of the range on the low side but going wider than recommended can sometimes be a problem with the bead not wanting to seal. Here are the specifications for BFG MT KM's:

If you go to Roger Brown's website (4Crawler) and scroll to the bottom of this link, you will see that the original "standard" rims were 6" with 3 3/8" backspacing. I know that my rims are 7" but I don't know the backspacing. I think 3 3/4 backspacing is o.k. but maybe someone else can confirm. Here's the website link:
