This is the second time this brand of tire has slipped off the wheel while on the Highway at 55 miles an hour or better. It put me as the driver at severe risk and the car has been damaged twice now. The tire size is Continentals Sport Plus 265/35 ZR 18. They were like new with little mileage. This is a collector item car and cost to repair is great, not to mention how it has forever created a fear in me, of having this happen again. I could have been severely injured if I was not such a good driver. I believe it is tire failure as the tire ripped from itself. There is still tire left on the edge of the rim. AAA saw the damage when they came to put on the spare. I will show it to my tire store this week as it happened on a weekend and they were closed. I will also have my car inspected for damage this week. I did take photos both times. Since this is the second time this has happened with the same type of tire, I believe it to be the tire being faulty and is a high risk for severe injury.
