So far so good Eddie. I took the wheels off completely when I detailed the wheel wells of the truck with TrimShine (I know, it's absurd) and since I had them off I gave each wheel a good cleaning inside and out. They still sparkle like new. I have been keeping my eye on them (especially the lip area) and I see no cracking, warping, and what not. They rode just fine on my recent 800-mile trek.
The only thing I can nit-pick against these rims are the center caps. They look great except there is some pitting along the bevelled edges of the caps as if the chrome didn't want to stick there. But this is truly nit-picking as it can easily be overseen. Just a head's up is all.
