To back up the age thing with tires.Just this week blue a E rated LT tire on the TV.It was 7 years old and good tread.So time does count Trailer tire or LT tires.Age plus heat adds up to sitting on the side of the road.:R
Some folks make a big deal about getting "fresh" tires. Since tires are stored in well ventilated warehouses, I don't think there sould be any concern about a tire that is within 3 years of its date of manufacture. Even tires that are at 6 years old - but unsold - are less of an issue than is commonly thought.
What really ages a tires is exposure to sunlight and heat. Operating a tire in Arizona is many times worse than a tire sitting in a warehouse in Minnesota.

My opinion on the alternate load ratings above 3,420# would be a bit suspect.......
I want to second what Roger said. I can understand higher load carrying capacitites if higher inflation pressures are utilized, but the physics of tires say that higher loading at the same pressure results in higher failure rates. There are some construction changes that will help, but the load vs pressure thing is so fundamental, it's hard to overcome.
