I bought my 2017 SS brand new in November 2017 when I lived in NY. It came with the set of 19" Bridgestone Potenza RE050A high performance summer tires.
Swapped them out almost immediately and put them away. They were stored wrapped in plastic in my climate-controlled basement. I have recently moved to Rock Hill, SC (about 20 miles south of Charlotte, NC), but decided my holiday trips to NY mean I will probably never put them on so I want to sell them.

Well less than 1000 miles on them. Currently going for over $1300/set on Tire Rack. Asking $800 for the set of 4.
Here are pictures of the set.
I don't want to ship these, so would expect you to pick them up or meet me somewhere reasonable close.
