4" BS and 12.50...yeah about 2" from the factory flares. 5" backspace is too far in, you'll rub on your control arms. 4" is probably the most you'd want to go without rubbing. I rubbed with 10.50's on stock rims with 5.5" backspace, 12.50's would be almost undriveable.

If it goes offroad, stick with the 15.8's on the 12.50's...better beat pressure and you can air down more.

I've seen jeeps with more tire sticking out of the flare than you're suggesting, with seemingly no issues with being pulled. I think that as long as you're not running chopped fenders with the wheels sticking all the way out, you're fine.
