I certainly agree with Gene's comments. But the comment of essentially "tires
are cheap, blowouts are expensive, so replace them often" makes sense only if
replacing tires on age actually improves the odds. Statistical data, if there
is enough to be significant, should back up the idea of replacing tires on age.
Looking at the average and standard deviation of the ages of tires in service
compared to the tires blown should tell something. What would happen, for
instance, if the age of blown tires is LESS than the average age of tires still
in service? It might say that newer tires are less robust than older tires
(??), or it might mean that there is a infant mortality problem and frequent
replacement actually increases one's chances of a failure. I don't know where
the data will lead.
Yeah, I know - too much time on my hands :-)

might be interesting ( because you can)
however
what will you do with the data?
you cannot control the rubber formulation (changes every year, with every
manufacturer)
you cannot afford the risk of a blowout (just to push the envelope)
the cost of this risk is $2K plus
all to save $100 for a new tire? (less than the cost of dinner for 2 ;>)
I am a big proponent of (do it because you can)
but I am a belt and suspender guy (no risk if no need)
have fun
