What kind of tires and wheels are you looking for? I have stock wheels I may be parting with in the near future. They're in great shape. You can see them in my library. Stock 255/70R16s on them with ~%40-50 tread left, worn evenly. I would be selling them just looking to knock some off the price of getting new tires when I install the lift.
May not be what you're looking for, but I thought I'd throw it out there. Be sure to check Craigslist often. You may find exactly what you want for a price you wouldn't believe.
