tires needed for the alternate car...

hey i was wondering if anyone knew of any good sites to get used tires on for my acura. ive got some pretty basic 17inch rims on it right now...the tires are shot in the rear and i need some used ones...any ideas of where i can get em? (preferably not ebay because i dont have an account)

i like www.craigslist.org for buyin used stuff... but only works if youre near a city that does it

alright cool thanks, i was gonna try craigslist because i live in northern colorado so thats perfect...
