Wheel Backspacing question

[93Chevy_1500]

Well I ordered the procomp 1069 series in 16x8 for my truck. I realized after the fact the the backspacing was 4" how much tire do you think will be sticking out beyond my fenders? I don't want to put flares on the truck. If they stick out to far I will send them back.
