I have a set of 4 Scorpion ATR M&S 275/55/R20 tires these tires have about 18000 miles of wear, they went into service in Jan 2007, there is 12/32nds of tread depth remaining from the original 14/32nds. I am asking $500.00 Canadian I live in Toronto Ontario. I would post a pictures but I don't know how, new to the forum.
