You will have tons theories on allowable tire age, but it all boils to inspection.
I had car tires who at 10 years had no cracks and I did not hesitate to drive high speeds on them. But car was garaged most of its life.
Than when I bought my vintage bus conversion - old tires had side cracks big enough to stick my small finger in them. Yet they hold 100 psi just fine.
I did follow with experiment and left 1 of old tires on tag axle. 11 years later sold the bus with the tire and cracks on it. Those were the years when tire had only last digit of year on it, so it could be 25 or 35 years old at the time.
But just for the test - I cut side of 22.5 tire to find over 3/4" of rubber with lot of fabric in it. So what 1/4" crack makes to 3/4" of reinforced rubber.
With variety of tires, you can't go by paper recommendation,.
Inspect, inspect, inspect.
Nobody would re-groove tires in California and regardless industry saying they have less % of failures than new tires - the gators on the road don't bring good impression.
Than when I had bus on 22.5 tires, who can last for 3-400,000 miles, instead of paying $550 per tire, I could get used, who at 3 years of age would still have thread good for 60k miles.
