A couple of days ago I had the left rear tire completely delaminate (down to the steel belts - all the tread came off at 80 MPH). Tire life unknown - bought car used last month. Worn on the outsides but still legal. 40 PSI on all. Destroyed the wheel well and wheel well cover panel. Was getting new tires this week with the oil change - the delamination beat me to it. Anyone out there heard of the Potenzias delaminating :?:
