A tire engineer I've spoken with uses a life of 10 years in northern parts of the U. S. and 6 years in the southern parts of the U. S. Storage out of the sun adds to the life, but that isn't quantified. Anyway, no one wants a tire separation, especially when due to an old tire we knew we should have junked.
"Older people who are reasonable, good-tempered, and gracious will bear aging well. Those who are mean-spirited and irritable will be unhappy at every period of their lives.
"Let each of use properly whatever strengths he has and strive to use them well. If he does this, he will never find himself lacking."
Marcus Tullius Cicero
