Hi CapriRacer, Earlier you said: "That probably also means that hyperinflating tires would result in a fatigue failure many cycles down the road - due to the overall stress in the tire caused by the inflation pressure."
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!
