Tires look brand new, but are 11 years old. Keep or discard?

I keep track of tire age on my vehicles and trailers. I tend to err on the side of caution. If it were my truck, it would get new tires. Here is the Discount Tires position, which I where I get my tires. They would not service them. And yes, I have replaced tires based on age that looked brand new, such as spares which never hit the ground.

5 years? Sheesh, I bet 1/2 the country's vehicles are riding on tires over 5 years old.
Another step towards “the wussification of America”

I have tires older than that on my truck and my stock trailer. I was mistaken. It’s 6 years on the date code where most tire shops recommend replacement.

I bought a bumper-pull 14k trailer in 1997 I think. Still on the original tires today. Very few miles on the trailer - tread looks like the tires are brand new. Trailer is stored in my pole barn so not exposed to sunlight or to any fumes of any sort. Every time I hook on to it and pull it out of the barn I check the tires very carefully for any signs of deterioration. So far no sign of aging at all so until I see cracking or something like that I'm going to keep using those tires. Goodyear brand...but I don't remember the exact model.

I've had the entire tread come off of one tire of my empty, dual axle dump trailer. Maybe 1500 miles on it, max. But 20 years old! Stored inside on concrete 99.9% of the time.
