Aging 22.5 tires - how old is too old?

I read an article created by:
Guy Walenga, director of engineering, tire products and technologies at Bridgestone Americas

In it he tells how tires "properly maintained, inflated, repaired and retreaded commercial truck tires may safely and reliably be in service for 10 years or more"

I am wondering if there is other data you may have. I know most 'sales' answers are going to be 6-7years then change. Not interested in what a company's sales answer is, more looking for what is the correct answer.

I have 7year old Goodyears on my DP and they look new, stored indoors and with less than 40K on them. Going to run them for a few more years.

There is no definitive answer to your question. Tire manufacturers can give you a tire life expectancy under perfect conditions but not in the real world. How many times have you hit a really serious pothole or scuffed a curb. How many times was a tire under inflated or carrying a little to much weight for the inflation.

We may think we are great about tire issues but on any given day a situation can arise that might impact tire life. The perfect time to replace a tire is just before it fails. Unfortunately that's not a viable replacement schedule.
