I have been driving a long time and I have never had a tire failure like this. I was driving on the freeway at 65 MPH when I heard a loud pop. The right rear tire started losing air quickly. I got into the right hand lane immediately and luckily just as I was coming up to an exit ramp. By the time I was on the ramp I presumed the tire was totally flat. I was running considerably slower by then and kept going to a gore area several hundred feet down the ramp where it merged with a two lane frontage road.. It was a close fit. I only had about three feet on each side with traffic whizzing by. The first thing I learned is that drivers do not know what emergency flashers mean anymore. Since it all started with a pop rather than an obvious blowout I got out a can of flat fixer to inflate the tire a bit so I could find the damage. It wasn't really that bad there was a hole in the middle of the tread that the flat fixer mixture was spurting out through. As I continued adding the entire can of "stuff" I noticed that the leak was slowing. I got the pressure up to twenty PSI and decided to drive on down several hundred more feet to a gas station. At the gas station I drove around to the air pumps. I looked the tire over really carefully, or so I thought. No blisters or bubbles, no obvious damage to the tire or rim. What I did not see was the minor scuff marks and discoloration on the inside of the tire at the very top. I started adding air to the tire and at 25 psi took another look at the tire. All was well or so I thought. At 29 psi I decided to give it just just a bit more air. That was when the blasted thing blasted. Lucky for me the massive tire failure was on the inside behind the tire and wheel. It blew directly on the opposite side of the tire from where the valve stem is located. That was lucky for me if it had blown on my side of the tire my family would have had to go out there and pick up my fingers if they could have found them. This was a three week old Michelin tire and I gave the guys at the tire shop holy he!!. They told me it happens all the time. I still can't decide whether there was that much damage done to the tire. Edit In the picture I am pulling out on the section of the tire to show the size of the damage.
