Will they fit?

Pauly, you're probably thinking of GDemon, pretty much what dwire67 copied (based on observation). But they aren't Crown Vic wheels, they are Chrysler 300 wheels.

Not sure what they did for the center register, though. I don't really know if you have to fix some interference or not if you use the Mopar wheels. Based on the fact that neither of them referenced any register work, I'm guessing you don't have to.

In both cases above, the tires are 225/50R17 and 275/50R17. The 275's are a bit exclusive, only found some Nitto's on Summit's website for a pretty penny.

Problem with Crown Vic wheel is (as best I understand), they were 16" up to 03 (I think) and when they went 17" they also went to a really high postive offset, like +50mm or something like that. So you can run a 16" with a more moderate offset, or 17" with a high offset.

And don't think you have to look for 300 wheels only, the Chargers/Challenger/Magnums used the same steel wheels.
