consumer warning / doomsaying about tire shelf life [NAC]

[thejimrose]

this is an interesting [albeit sensational] piece. scary that they were able
to buy tires as new that were in fact many years old.

it piqued my curiosity and i thought i'd bounce it off the collective. has
anyone seen any data backing up the claims to 'replace tires after 6 years
no matter the condition' ? is that common sense or 'please buy more tires' ?
