I sold my stock P-zeros off my V6 a few years ago for $500 or something. Not sure what you could get for your all seasons and rims, but you should be able to get something.
What wheels are you getting? If you're still deciding, check out ModBargains. They set me up with some Forgestars and Michelin PSS tires. I don't have them on yet, but they'll be here next week and they're going to be sick
