Thanks for the replys.
It's really weird, the outside edges are fine, but the second row of tread in, on both sides, are worn through, and showing steel wires (belts). I've never seen anything like that. Maybe it is a bad tire (they haven't been under inflated, I have the pressure pro monitor, and have always kept the tires within a couple of pounds of correct). I am going to take the tire in to my tire dealer to see what he says.
Thanks again for the input.
