Just testing the market. I had these 21" Grey Arachnids mounted by Tesla about a month ago and have put a couple thousand miles on them in that time. No curb rash/dings/damage. They're on a 2012 Model S, so I don't know if the TPMS are different than the later models that display the pressure inside the car or not. They are staggered width. Would include the center caps of course. I'll ship them to you for $4000 or you can pick them up from me in Nixa, MO (or some nearby location where I can easily drive to meet you) for $3500. I realize used are not as desirable, but I wanted to try them out and while I like the looks, the energy hit isn't worth the appearance given how often I need that extra 10 miles of range.
