I was very anti the Chrome Clad Plastic wheels. I got them in the end and from what I hear they are easier to take care and actually last longer and don't crack like real ones.
Just think if it are drunk and scrape the F out of one on a curb it will be an easy/cheap fix. .......8)
Just get a new Cover, assuming you can even by them from Mopar.

All and all I wanted the 18" Wheels but when I saw mine next to an R/T with 18's it just didn't have the same impact as a Chally with 20's.
So I'm glad I got them. I will put new wheels on in about 2 years anyway and will be glad I got the bigger tires then for sure.
