Rusty Lug Nuts?

I purchased new wheels from 4wd.com last month and bought some black lug nuts to go w/ them. Got my new tires mounted, was quite happy with the look... until yesterday.

It hasn't even been a full month and these Pro Comp Black Lugs are rusty? It's not as if it's been extremely rainy here in SC, nor have I driven the Jeep anywhere but normal roads. Every lug on every tire looks like this. I'm at a loss for words.

Is this normal?

(and yes, I've emailed 4WD... awaiting response)

Well lug nuts usually have a coating to prevent rust such as a chrome plating coating. My guess is that they were scratched while you installed them and that knocked off the anti rust coating.

You can paint them but you would have retouch them every time you put a nut drive on them and that's a pain.

Anyways, if they were badly scratched during installation then yes it would be normal for rust to build up on the scratched sections.

Do they salt your roads in your State?

The finish on your lugs was damaged by the airgun socket used to install and tighten them. This is such a common problem that I will not take my vehicles with chrome lugs to anyone using an airgun. I do them by hand in my garage...sounds a bit anal but your lugs will get ruined every time an airgun is used on them. I assume that the airgun lug nut socket should have some form of protective rubber in them to prevent the damage that occurs, but from what Ive experienced it must wear off.

Those look like Gorilla lugs. You can't put a regular socket on them. The lugs should have come with a special socket to fit them. The rust is definitely from the impact of the air gun.

No salt on the roads... and the airgun def makes sense.

Fair play to 4WD, they're sending me a new set. Guess I'll be putting those on myself, nice and gently.

Thanks all.

There's no doubt that an impact wrench is harder on lug nuts (I use my air gun to blow things off with compressed air). I'm running a cheap set of wheel locks (why, I'm not sure; this is the first set I've ever run) and after only 5 or 6 uses with the impact wrench, the chrome plating is chipping like mad. I do torque my wheels by hand, but I remove the lug nuts and run them back on lightly with the impact.
Those splined nuts like the OP is using are even worse because they have less surface area in contact with the socket, which point-loads the socket/ lug nut interface. Bottom line is, if you don't want to damage the coating (chrome, powder coat, etc.) don't use an impact wrench. If I was still running wheels with exposed lug nuts, I'd be running stock style lug nuts with stainless steel caps.
