At this point in the season - we're six weeks away from spring - it's too late for you to sell these as whoever would have wanted/needed a set of winter wheels and tires has one.
However, since I just recently purchased my FX (late December) I can tell you that there were two local (Montreal) ads on kijiji for the same set of 18" oem wheels and Toyo winter tires in similar condition to your iPikes. The first seller wanted $1600 (yaa...no!) and the second wanted $750. I contacted the second and he told me he sold them less then 24hrs after posting the ad. I went back and forth with the second who had posted the ad a month prior and bought them for $1,100. Since I need to have winter tires by law, paying a bit more for used vs paying substantially more for new made sense.
tl;dr: My $0.02, you need to lower you price, it's way too high, especially considering the wheels are not oem (higher value).
