Calvin......buy 1 or 2 spare wheels used otherwise you will pay Tesla's over bloated price when one breaks. I got 4 wheels, tires and tpms for $2K on ebay. You just need to make sure you get the new version of the tires and sensors. And yours are staggard, there is a set on this site for $2300 which isnt a bad price.
This is not my car, just found the video on YouTube. However I agree with you about Tesla's pricing on wheels being high. Also where I live in Wisconsin I would only consider the 21" wheels for summer and get a set of 19" with winter tires for the other half of the year.
