Tires - The 10 Year Rule
Hey gang, Regarding big, DP tires... I know most adhere to this rule and some prefer to replace tires within 7 years or so of date code. Others replace the steers every 5 and the drives every 1...

The one thing that has yet to be mentioned is locale. Heat, in the form of ambient temperature, plays a HUGE role in how long tires last. Obviously tires operating around Phoenix experience a lot more heat history that tires operating around Minneapolis. So if you live and/or operate in the desert SW, you need to use a more rapid replacement schedule than someone living/operating in the northern midwest.
And why don't today's tires last longer?
1) Law of Physics (and Chemistry) don't change over time.
2) They didn't, but we have the Internet today and that changes how people perceive things.
3) Then there is this odd thing that our brains do: We think the Good-Old-Days(TM) were better - somehow. Actual statistics don't bear this out.
I think he meant that tire technology has improved and tires last longer than they did in those days of yore.
Also... this from the OP...
"Babied and covered most of their lives, in beautiful (where visible) condition with no checks
Entire lives in Santa Cruz with a very mild climate. Last couple of years undriven and parked without the jacks down and uncovered with driver's side facing south (the sun... and Central California coastal fog)"
