luvbelly, I was thinking the same thing. I was cleaning off the wheels quite regularly, and they still look like this. Interestingly I have been in contact with Wheelpros (they distribute KMC) and they guy told me that even non-chrome wheels (I was asking about the Monsters) would get eaten up in the winter. Um, my factory wheels are 3 years old and look like new. Based on this I think aftermarket wheels are of much lower quality than stock wheels. BTW, Wheelpros is NOT replacing the wheels but did offer to "help me out" on a new set. And it only took 3 months of e-mails and phone calls.
I planned on using these for one winter and then picking up some winter tires for my stockers and then just switch when the weather turns. Instead I'm looking to try to refinish the XDs with either wheel paint or some sort of bedliner coating (hey it can't look any worse than they do now!).
Lesson learned: Unless I live in a completely salt free environment don't run these delicate
chrome wheels.
