Are these really plastic covers on the RT 20 inch rims? They look like chrome rims but feels like just a cover?

It is a chromed plastic molded outer that is permanently bonded to a full aluminum rim. The reason is that Chrome rarely sticks to aluminum well (plus Chrome causes aluminum embrittlement) manufacturers all switched to this design because it causes less warranty issues for them.

That is why I am saving ($2000+) for the Yellowjacket rims for my Challenger! :thumbsup:

The YellowJacket rims are cast. All other SRT rims are Forged. So if weight is a concern, all the previous SRT rims will be lighter and stronger.

Naw Brett.... I don't really care about the weight! I LOVE the look of the yellowjacket rims! (and truly dislike those Chrome Clad rims) :)

Aluminum immediately forms a passive film onto which it is not possible to electroplate. The first step therefore is to apply a zincate coating, or such alternatives as Atotech's Alstan.

Once the zincate finish is in place you can copper-nickel-chrome plate, starting with cyanide copper, but there seems to be movement towards electroless nickel-nickel-chrome instead.

Yeah they are plastic chromed cladding.... Imagine my disappointment when I found out these were the UPGRADED wheel. Ripped off for sure.

I'm debating picking up a set of 20" replicas since I don't want to splurge nearly $3k on a set of oem stock srt8 rims..

My one clad wheel is all dinged to sh*it anyways.... I don't think my dad took care helping me move them to my shed with the wheelbarrow last winter..

They look nice on a sunny day when they're rolling along.... but other than that, I hate them.

The problem isn't even so much the oxide layer that the aluminum protects it's self with it's the fact that it's not a great uniform conductor. That coupled with lots of shops full of shoddy labor and you usually wind up with rims that look great for a very short time before they start to peel. The other thing with chrome is on aluminum is that just like with steel, if the aluminum gets exposed it will oxidize and the chrome will then start to flake just as it does on a steel rim with a nick.

It's just "easier" and less "hassle" for the OEM's to use this new clad process because it's easy to chrome plastic and it holds up longer and they have less warranty issues to deal with because of defective rim finish.

I think I will just go with aftermarket rims and keep my tires.

Heritage wheels on the R/T Classic- -the best wheels IMHO. Classic looks, forged, polished aluminum- - but they don't like curbs.
