If your trading because of the ride, do not do it, it looks horrible, I have my 16" winter wheels on and I hate it. Buy a set of new tires, the stock badyears are the reason, my 20" rims and tires ride better due to the tires.
Looked at several ex wheels over the weekend..Tires on all of them have been wiped out. If you are interested in trading me and have worn out tires then add $350 plus your trade. This is equitable since my tires are obviously brand new condition. Also not interested in having to ship, prefer locals only southern california
