In this huge military aircraft graveyard in Arizona most of the aircraft aged out and we knew when they were going to do it. But, the materials that age out are much more predictable than DOT certified tires. (LOL)!
Aircraft Graveyard When a tire manufacturer is mixing up a lot of different compounds for building tires and those mixtures are, for the most part, confidentially known only to the builders, then they should be able to put a ball park figure on how long they will last (age wise). Michelin will not put an absolute figure on it but their most often published number is 10 years.
The six year number for shelf life of new, unmounted tires is not firm, but is most often mentioned.
The ST tire manufacturers are pretty close to unanimous on predicting a 3-5 year life expectancy for those issues. Where did that come from?
It’s a big country and the aging issue cannot be solved for numerous reasons. Maybe they should start by setting geographical regions and working from there.
