2013 Ford F-350 Tires & Wheels Problems

1. The tread seperated from the tire at 60mph on highway. small vibration prior to incident. 2. Extremely dangerous to all. Vehicle was towing loaded horse trailer, middle lane. 3. Tried to bring up to Michelin corporate with little help available. 4. I will be taking tire to vender/dealer for inspection. have photos available. 5. only warning was small vibration that became present at 50-60 mph and went away at lower speeds. Vehicle did not vibrate on prior day. thought is was out of balance wheel.
