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.

    We had an engineer from Michelin in to talk to our group about tires. He said they should be good for 5 years and then from 5 to 10 years they should be inspected annually. He said the inspection can't be an external visual, the tire has to unmounted and examined from the inside.

    I know two MH's that had front tire blow outs. Both totaled and one killed. The recommendation where we are is that when the front tires reach 3 years move them back. We had a tire fail on our tag and it did thousands of dollars of damage, but there were no control issues.

    I also measure tire pressure every trip. I know the weight by axle of our MH and go by Michelin's chart on tire pressure.
