Anyone had much experience with the NT01 heat cycling out?

Old tires can be fine IF they've been used daily- as an engineer here at my workplace explained, using the tires stretches them and heats them. This keeps them pliable as it works around some sort of chemicals (I think he mentioned enzymes or amino something) that they put in the rubber formulas to keep the rubber pliable.
If the car sits for a long time, this is bad, in the case of the car that gets driven once a year or is in a museum all its life- the aminos or enzymes or whatever are lost out of the rubber from no use and no stretching or working of the rubber, and they go dry hard.
Which leads to the Paul Walker situation of the Porsche that sat babied in the garage and taken out once a year to a show, and the rubber hardened over 9 years of that.
Personally, I put a set of four BRAND NEW tires on my Chrysler project/drag car in 2014. The car has not EVER been driven or even rolled on these new tires whilst I rebuilt the engine and resprayed the car and restored the body on stands.
I've just had to throw out all four brand new tires with zero use (the car never even touched the ground with them) as they all dried out and cracked and you can see from four feet away deep fissures in the sidewalls and across the tread. From two years of sitting in a garage!!!!
Make of that what you will, but I wasted $1000 on tires I never even drove on and they perished and they're in the garbage now, brand new.

^ That's gotta hurt... I've got some old Star Specs on mine that have been sat for a while in the garage as well. I got a season(ish) of use out of them though, so I'm not too upset about replacing them once I get the car running.
