Roush mustang wheels fit a 2015 5.0?

[Kuda427]

So
I'm tossing this around
I found a like new set of Roush wheels with tires for sale
I know that they are 5x114.3
So...that part if fine
Wheel size is 20x9.5 on all 4 corners
Tires are 275x45r20

Looks like they are a 45mm offset.???

I realize the front tires may be too big...but tires can be changes..
I can get this set for a steal of a deal
And I think they would look great!
Question is...Will these fit??
Any insight would be great!!

A little more info

All depends on the dimensions. Are they the stock V6 rims? GT PP rims? They come in a half dozen different sizes. You just have to see what your car can accept width and diameter wise.
