How many miles?
I just sold mine with 3000 miles. I listed them for $400 and sold them for $350. I could have sold them for $400 if I had waited more than a day. FYI I replaced the oem tires with Michelin LTX AT/2 in 235/80/17 . Yes, it looks pretty radical.
For general information:
I sold my set of four OEM tires (Duelers) on Craigslist for $400. Took about five days, had one scammer and about three guys interested, the first of them to bring the cash got the tires. The whole process was easy.
