Will 4" of backspacing be fine with 33x12.5r15lt on stock JKU?

Looking to upgrade my stock tires and rims and found a deal for cragar soft 8's and was wondering if the 4" of backspacing is not enough for 33's. Any help would be appreciated

I don't think a 15" wheel will clear the Brakes ( Calipers ).
