Where does that six year number come from? Somebody just pulled it out
of a hat, that's where.
I have seen tread separation on tires that were poorly stored, in much
less than six years. I have also seen tires much older with no separation
issues.
What you want to see is a plot of the separation incident rate versus the
age of the tires so you can make an informed decision for yourself rather
than just taking a scalar number from a reporter.
In addition, if you are driving older tires, or even if you are driving
brand new tires, you should inspect your tires whenever you check the air
pressure, which should be pretty often. Pay attention to how the car
drives. Often with tire problems you will get a good bit of warning that
something is wrong, but too many drivers just ignore the signs and keep
driving.
