nascar wheel fitment

I found some nascar wheels. Dont ask what their for, and please dont say the'll look ugly.
They are 15 X 9.5" wheels with 5x5 pattern , and 4.5" backspacing.
The tires they say are either 28x10 or 27.5x12 both fitting 15" wheels.

Will I have a problem with fitment. Im horrible with tires, and didnt get anywhere with the stickies.

5 on 5 is large Chev bolt pattern. They'll fit on most B-bodies and most GM trucks with a 5 bolt pattern.

They're not going to fit on your F-body at all.

is there any way to properly correct this? and if so what about backspacing? is 4.5 sufficient?
