In fact I read the entire NHTSA primer on pneumatic tires (all 707 pages)and the accepted wisdom is that degradation occurs faster after 5 years but the recommendation is still to inspect them regularly, keep them inflated to the proper level, and replace at the first signs of aging issues.
A lot of tire degradation happens inside the tire, and since I don't have X-ray vision I replace my trailer tires on a time basis, and a very conservative one at that. Between three and five years, tops, and never more than thirty thousand miles.
Ah, but there are other recommendations to address that as well and those issues are a result of abuse but I will not suppose I could possibly quote all 707 pages. You can educate yourself or swap tires every 5 years, 3 years, or any interval you choose. I will say tires are way more complex than I ever dreamed and the technology has progressed immensely over the years and there is real science behind them. The breakdown occurs in quality control inspections and routines as many tires have anomalies in them that will not affect their durability and service life. Anomalies that do affect these issues should be viewed as defects and not be sold. I think the Chinese have a quality control issue that Thailand has conquered.
