AR-767 wheels

I'm looking for some opinions on a 4" backspacing on 15x8 wheels wearing 33x12.5 tires. Do you think it will rub. The guy at national wheel and tire told me the smallest backspacing I could get on those wheels in 4" I was originally thinking 3.5" but was wondering if 4" would be ok. I'm using the superlift 5.5" superrunner lift.
THANKS

That rim is only available with zero offset (3.5" backspacing is not available).

I think Eaton makes a similar rim with custom backspacing avaialble.
