Wanted : Source for Used Race Tires

[lbevins]

Does anyone have a set of used tires or know of a good source for used race tires? I'm talking anywhere from FREE to maybe $40.00 each. Must fit a 15 x 8 Fuchs rim, so any of these sizes : 225, 235, or 245 x 15 (the wider the better). I want "stickies", so I'll try any of these : RA-1s, R-888s, Hoosiers, or Yokohama Advans. HELP! And thanks!
