Started driving my 2007 Saturn Ion from tampa to orlando. When I notice a vibration through out the vehicle. It gradually grew worse so I pulled over. At which time something flew out from under my car. Coming to a stop, I checked the car out and saw nothing wrong. I started driving, in hopes to make it to the next exit, but it didn't. the vibration got ridiculous and I pulled over to find my front driver side tire flat. Upon removing the tire, discovered a large piece of threading was missing along with other damage to the inside of the tire. Which is why I did not see it the first time I pulled over. Tire is the good year assurance.

I noticed a vibration on my steering wheel. When I checked the tires I noticed a bubble (tire separation?) on the inside front passenger tire.

I have had 4 tire failures on my 1997 Saturn Ion. All tires were Goodyear assurance 195/60/R15 tires. In ones instance, a tread separation occurred. In two instances, bubbles developed on the inside sidewall of a front tire. The fourth instance also had sidewall damage, but whether there was a bubble first is not know.
