Ok, that's what I suspected. Yes, the soft metal at the top of the lug nuts has crossed over into "evil" in my book. I've already ruined 4 of them. (Luckily I have an "extra" 20 from the 19" wheels I bought used.)
I hope Tesla comes out with new ones that don't suck.
If you are desperate, you can buy a pack of the official Tesla "black plastic lug nut caps disguised to look like a real nut" and slip them over your dinged ones. Looks OK even on silver wheels although they only come standard on 21" gray wheels, and they are cheaper than a set of new lug nuts. If you want to try them out, you can park next to a recent dark-wheel demo car and swap them on by hand to see what they look like.
