Cragar SS Wheels 15x8 4.250 backspace

Anyone running these on the back of there 1967 Barracuda? I just ordered a set from Summit (Clearance sale!!!!!!!!) $127.00 each! I am hoping to fit P255/60/15 tires (BF Goodrich radial T/A's). I hope they fit! Im running super stock springs. What do you think? WIll I have any clearance issues?
