Hey guys. I'm looking to purchase a set of 21" wheels and tires, grey or silver, for a Model S. I just ordered a P85 with 3700 miles on it and it will be here in a little over a week. We could swap out the factory 19s for the 21s plus a little extra cash, or I could just buy the 21s outright. I'm trying to save on shipping from the mainland. Thanks.
