I happily let the tire center have them for recycle or ???. I probably could have gotten a few bucks but would have to transport back to the house and store them and blah, blah,. blah. These would be great to purchase just to do major burnouts, though. I wouldn't even recommend for daily driving. I hated the P-Zero (as in zero traction). I only had 5000 on mine as well when I threw on the new Michelin Pilot Sports and never looked back.
