I am not just sure what your question is....
Do you mean why did it "blow"?
It sounds like it did more than "blow". It probably blew, as in lost pressure, some time before you saw it disintegrate. Why it lost pressure is anybody's guess.
Even that disintegration comes in two kinds. Some shred the side wall. This is more common to passcar tires run below load pressure. Others separate the belts/thread. This is more common in heavy tires. and very common in dual set where a tire can be run out of load pressure for an extended period.
Think about that last one...
Most of the tire weight is in those belts.
Do you know what a 22.5 tire weighs?? (hint ~ close to 100#)
Now think about the that belt that is 2/3~3/4 of that tire weight.
On the top side of the tire, it is going twice road speed. That just helps tear it loose. It only hits the fiberglass body at road speed. I was always surprised how little damage that did. I'm not testing cars any more.

Where in the world did you get your information/facts? Not one thing you stated is accurate. I worked for one of the big 3 tire manufacturers for many years. I think I know a little bit about tires.

Hmmm 202 in Phonix last week, Temperature 100 + average speed on 202 80mph.
My guess under infaltion, excessive speed, high temps.

when one comes out... please let us know. As far as TPMS being good... you seem to be in the minority. Tell us what "qualifies" as good?

The take away from all the destruction is, don't over look your tires. Replace them at 7 years or before especially on the steer axle. Check your inflation PSI every morning before travel. Consider investing in a TPMS. Review the Michelin blowout video and practice what you would do.
Safe travels.
Steve... what is with the 7 yr recommendation? What is this number based on? Why not 3.5yrs or even every year??
Have you ever checked a date code on a tractor trailer??

Some guesses are just better than others.

Very few MH tires "blow." My bet would be old age or under inflation, or both.

Check with any tire manufactor and tell them you had a blowout whith their tire; you will get all the reasons you could possibly think of.

Ray,
Could you please be specific about where you disagree.
Where do I get my information? From being an engineering manager of one of the largest independent testing companies in autoland. Did you happen to hear about the Explorer/Firestone issue? I'm the guy that designed the experiments that found the root cause.
So, please if you have a difference point of view and information to share, take advantage of this forum and share it.
By the by, we did a similar set of tests later for a major coach builder that had a tire warranty issue. That is when we photographed (via high speed digital cameras) and weighed and measured and examined lots of different things.
