Can I fit 15" wide tires, probably 37-39.5" tall on my 8" wide rims? Or do I need 10, or 12 inch wide rims? What have you guys done?

Oh I know its not recomended by manufacturers to mount a 15" tire on a 8" wide rim I just wanted to know if anyone has done it and what kind of success they have had with it.

I have 15x42x15's on 15x8's... Fit fine. Hold the bead real good, and don't look too ballooned either.
You can tell from this picture... I don't see a problem. I also wouldn't have a problem with a 10" wide wheel.

Best picture I have available. 39.5x15.5 TSLs on 15x8 wheels. Most guys in our club will tell you that a narrower wheel is better off-road in regards to holding the bead, protecting the rim, and keeping crap out of the beads and causing air leaks. Another guy has run 15x8's with 42x15.5 Swampers for years and never had any issues, including never debeading a tire and he runs very low teens to high single digit air pressures on a heavy fullsize trucks. Another guy ran 15x8's on a set of 35x15.5 Swampers for awhile, only switched back to 10's because of frame clearance issues.
Do keep in mind that all of these are primarily trail trucks, but all are street legal and do see some pavement miles between trails on a regular basis (almost all of our trails within a couple hours drive require some pavement). The guy with the 42's made several long distance trips on his before getting a trailer.

killed 2 birds with one stone on this one, i had the same question. thanks everyone
I ran my 42x14.5R15 IROKS on 8" wide wheels for a while and now I run them on 10" wide wheels.
I like the 10"s better but the 8"s worked too.

These pictures were taken last weekend and show the benefits of 8" wheels and 15" wide tires.
The front has 8.0-8.5 psi per tire.
The rear has 3.5 psi per tire.
See how the rear passenger tire is folded under and still holding the bead:
