With the chance of sounding really stooopid I will ask anyway. I have always had GREAT luck with the Avon tires and they last between 7500 and 8000 miles. This last set I had wore out REALLY fast, less than 3000 miles. They almost look dried out or at a rotting stage and have the cord showing in three places. They are not worn like any of my other tires, all from the middle and hardly anything on the sides are worn. For those that want to beat me up about checking my tires, well I do check them often but this really caught me by surprise. Anyone have anything similar to this happen with tires in general? I have thought back, I keep the tire pressure within 2 lbs of what it should be. The only thing I did that was different this time was scrub them with (here it goes) simple green. I have not read anything that simple green eats rubber, but could this be the cause? At this point Right now I have reached the conclusion that they where just old tires, but would like some input from the board also.
