I'll say what others are failing to... I think larger than 15" diameter wheels look horrid on older cars. I don't even care if it's a car that I don't care for in the first place, like a Mustang or Camaro. To me, it makes them look like a damn toy off of the K-Mart shelf. Not to mention they ride like $hit and you feel everything that is wrong with the road.
I think your Fury would look good with some 15" Magnum 500s or Torque Thrusts on it. This is an opinion sure, but I've lived and breathed old cars since I was a little kid, and made my living working on them for over 20 years, so it is stuck in my head as to how I think they should look.
I think the larger wheels look fine on a new generation 300 or a Challenger, as they have the larger wheel openings that can accommodate a taller tire, so you have some sidewall left when going to the bigger diameter wheel.
