Well said!!And that's why I decided to get out of the business, "experts" like yourself. Tires are simple device no one has really been able to better in concept. It's high pressure air, held in a bladder. Take away the high pressure air in the equation, such as a puncture of seal failure and you're putting an incredible amount of pressure, better than 1,000 lbs in most cases, onto an area of rubber no larger than your small finger, by the lip of your rim carrying at least a quarter of the weight of your car. The weight coupled with the rotational movement of the wheel is going to act like a very very blunt saw blade. Hence the resulting multi piece tire.
Happened to my father while taking me to the airport years ago at 50 mph, a three finger wide hole cut by a piece of metal on the road into the sidewallCould have been road debris sidewall cut ) deflation.....no alert on dash or was it sudden deflation?
