When does spare tire "age out"?

Typical numbers I've seen is that tires age out in 4-5 years whether they are rolling or not. Manufacturers say anywhere from 6 to 10 years after date of manufacture so the 4-5 years probably lines up pretty well with the lower of that range given that most tires aren't fresh at purchase.
