Found these on craigslist, a set of 20" wheels with tires with lots of tread for only $300. I'm not crazy about the style or Lexan tires or the rough ride with 20"s, but heck, for $300 for almost new set of rubber with rims would be a great deal for someone. Winter wheels if you wanted to save your chrome from all the salt, road set to swap out your fat/skinnies, cheap burnouts/etc.
