But by hyperinflating a tire, it will wear so little and last much longer than a tire at "normal" pressures. So even when it does fail due to stress and number of cycles, it still lasted longer than the "normal" tire.(and gave savage mpg) From my experience (not a lot!!) i reckon i'd be scrapping a tire because it has aged and become hard instead of wearing out. I do 30,000km per year so my tires are lasting a good while.
Anyway, i respect all you have to offer here on this subject since you DO work in this field and know far more than i do. Cheers to learning more!

You've glossed over a point that I think is important here - What happens when a tire fails?
Most of the time the vehicle can be brought to a stop with no damage to anything (other than the tire). Sometimes, the tire deflation will allow the rim to contact the ground - and that's gonna mean a new rim.
Sometimes the rapid release of the air will damage the fender - not to mention what the pieces flying off the tire are going to do.
But every so often a tire failure will cause the vehicle to go out of control - perhaps even flip over - and we all know what else might result.
Please keep this in mind as we discuss this issue. I don't want anyone to become a statistic.
