Final advice needed

So essentially if I was and I am wanting to get a 16'' rim, what would be the exact or possible dimensions???

The stock wheels for Isuzu are 15", 16", and 18", 7J (rim width), 6x5.5, ET+38 (offset), back spacing (5.5), D100 (center bore).
I believe for the 245/75 the best would be 7J, ET+25 through ET+38 or 7.5J ET+20 through ET+32. See picture to convert ET to backspacing:

Normally, if you go with wider tires you should end with wider rims and lower offset (f.e. for 265 tires it would be best 7.5J or 8J and ET=38-(265-245)/2=28).
The center bore should be not less, but common 108-110 are OK (you hardly find 100 exactly, but beware of the wheels with D78 - they will not fit!).

I'm personally running 245/70R16 on 7J ET+20 and I wish the bigger offset since my car become dirty a bit quickly.

Easiest way is to find a good shop that will go out of its way to sell you what you want and carries what you want and have them mount up several tire/wheel combos and test fit them! Then you know if they will fit.

I dont have any nearby shops that have 6-bolt rims in stock for text fitting....I live in Southern Indiana and there are not many shops. There is a pep boys (the largest around my area as far as automotive shops are concerned,) but they only display tuner racing rims 4&5 bolt rims and only about 7 are in stock of those. Im certain I will have to purchase the rims off line. I like the rock crawler set up to the one above. Not to incredibly picky I just am looking for a set under $500.....

Yup, I went through the exact same thing. I was almost just going to order one rim, do a test fit myself, and then go from there. You just need to find a place that will let you do a refund, but you will eat the cost of shipping back and possibly have a restocking fee too.

I actually found a Big-O Tires that had the AR Teflon Chambers on display. I asked the sales guy behind the counter and he assured me they will fit Isuzus. That gave me enough confidence to just order the rims. I was still nervous until the day they came in and I did a successful test fit in my garage.

Sometimes, you just have to say "eff' it" and order the rims you want. Worst comes to worse they don't fit and you can sell them on eBay or something. Its a huge pain but if it works out you will be rolling on the wheels you want.

Well if this has the same deminsions as Bart (nfpgasmask's) chambers then why would this not work. I will gladly trim the cladding a little to fit this. I dont understand the offset to backspaing issue? Nor do I get hub cntric or not? Thanks again.
