We had a little excitement on our way from Custer, SD to
Woodland Park, CO when the left rear tire decided to have a
tread separation. That led to a blowout when the ply cords
were exposed to the pavement when the tread departed.
This is a problem that a tire Pressure Management System can't
help with because there is air [pressure right up to the point
the tire blows. Even temperature measurement system don't
catch this type of problem as the point where the thread starts
to separate are too localized to cause a noticeable temperature
change. Once the thread separates in a small area, the
destructive loss of enough thread happens rapidly.

Losing a tire is one thing but a thread loss tends to cause a
lot of damage as the thread flaps around before is breaks off.
Since this was the rear tire, the flapping thread took out the
end of the wheelwell.

We were lucky the flapping thread didn't damage the BigFoot jack
because we needed it to change the tire.

You can see that not all the thread separated.
Here you can see there the belt ruptures when the cords are worn
away by the pavement.
