wow, way to play on the heart strings of people. maybe I am a bit of a dare devil, but I have run tires on a vehicle that were nearly 40 years old.
 
I feel for these families, I seriously do, no one shoud have to bury a family member.
 
BUT
 
I would like to know what the tire pressure was in the tires that the tread came off of, also if the tire had the proper load rating for the car/truck/van it was on?  People are so quick to find someone/ something to blame when tradgety hits, but quite often it is pointed in the wrong direction.
 
If I was to put a P-metric car tire (non lt) on my pickup, and run it at 20 psi for a long period of time (200 mile trip) it will delaminate the tread. too much weight and too much heat will cause this.
