Hi Team, I am searching for a second hand set of winter wheels. I found the wheels in the pictures below, oddly they seem to be the original 19" Model S wheels (which I want) but in grey (which could work for me). Anyone know if Tesla did these from factory or are they modified (painted). Also if anyone has a link to a summary of all wheels ever sold on model S that may help solve the mystery. Center caps are silver, which seems odd if they are factory. Thanks for any tips!
