Tire Blowout problems of the 2006 Hyundai Tiburon

Was driving east on I-70 car started shaking and heard a low roar. Thought it was the road. I got off exit 124 I believe and checked tires. All looked normal. . Checked tired pressures all was 32 or 34 psi. I though maybe it was the road so I continued to exit 126east on I 70 got off exit because I heard the same noise. I then drove the car around the truckstop and listened to the tires. . Rear passenger was making a horrible noise so I decided to turn back around and come back home even though the tires looked fine. I pulled out of the truck stop and over the bridge to go west on I-70 heading about 20mph and heard a loud pop. The tire blew out. . Continued over the bridge to the pilot truck stop and noticed there was still air in the tire. . I proceeded to take the tire off and found that the inside of the tire split at the seam. These tires are dangerous!!! the entire side blew out. . But there is still air in them. . Firestone should not be allowed to make tires anymore. . If I would have been going 65mph I would probably be dead. Firestone 215/45r17 potenza.

Driving west bound on interstate 10 fwy approximate time 2:30a. M. I had a tire blowout. The blowout in turn made me lose control of the vehicle and I went into a spin causing me to crash into a post on the side of the fwy. Upon crashing into the post my head hit the steering wheel at which time the airbag did not deploy. I have never had an accident in this car before, my assumption was that the airbag functioned. The airbag feature in my car proved to be totally non-functional.
