Tire Blowout problems of the 2001 Ford E-450

I was driving down i94 in mpls, when the tire blew. I had 3 kids in the RV and a boat behind. Almost lost complete control of vehicle. Was able to steer RV to shoulder of road. The entire tire had been completed demolished. It looks like complete tread separation, similar to other firestone issues. Tire damaged underneath storage compartment of the RV, cost me $200 for emergency roadside repair, approx. $2000 in damage to vehicle, and cost of a new spare (which I haven't bought yet). I was travelling the speed limit, no road issues, no objects - nothing. Tire completing separated with no provocation. I could have been killed, along with my entire family.

I had two of these tires blew out within 400 miles of each other. If ypu put the tires side by side the damage to tires look almost exactley the same. Ther is 10,000 miles on these tires. The sidewall on both tires seperate from thread.
