Thanks for the info! This is pretty much consistent with my research on the MXM4s vs Contis. I think it depends on where you're looking for prices, but they are almost exactly the same price in most places, meaning the price difference is negligible between the 2 sets of tires.
As far as tread wear goes, I'm hesitant to trust treadwear ratings as an accurate gauge of value given that a set of 4 of each tire is going to cost almost exactly the same brand new. I don't think it's fair to say that since the treadwear rating on your tire is greater, and you have less miles than the difference in warranty rating on your tires vs my tires, that this should mean that they are equal or greater in value. (I'd give you credit for MAYBE $50 because of the treadwear/warranty difference and the miles you have on your tires??)
There is also the difference in value between the 19 inch sport wheels and the 18 inch Aero wheels. Based on Tesla's valuation, the difference is roughly $1-1.5k in the wheels alone. I'm not expecting that someone would pay $1.5k to do a straight up swap, but as long as we are considering market values for this equipment, I think it's certainly fair to consider.
So once again, I think it will completely depend on condition. At this point, for Aeros in perfect condition with less than 5k miles, I'd be willing to make a deal with some cash on your end (we can take this into a DM to work out the details).
