One of the first things I bought my sammi was a set of 16x8 Mickey Thompson Classics by Alcoa. They look similar to your AR's. Then I found this BBS and discovered something called backspacing (I had not considered this before)......now I have to put them up for sale on Ebay because they have a backspacing of 4 9/16" !!!!!BUMMER.
Do you know the BS on your rims?
