Good suggestion on the Brand change, want to see how this sorts out first.

dog bucks, on the side of the tires is a DOT manufacturer date. Can you post a photo of it?

Is your car garaged? I have a friend with a 981 which was always parked in a carport, and the afternoon sun would shine on the front tires. The front ones experienced what I would call severe dry rot, worse that what you have. The rears which got little sun had zero dry rot. Either way, this is unacceptable.
" If you leave the car ( horse ) in the same place every time..... most of the time you'll be able to find It". Not the case here though.....is garaged. Thanks.

Try a different Porsche dealer. Instead of telling them what it is and what you want, just show them the tires and ask them if they can figure out what is going on with the tires?
My prior Porsche went into the dealership ( I did not buy the car there) for a minor warranty issue and the Service Writer said "You have a pothole strike "bubble" on your left inside front tire", and showed it to me. He said "You have to replace that tire, its not safe". OK. My tires were 2/3's worn, at about 4/10's tread depth. I didn't want to replace all four yet, but understood about the sidewall bubble. He then said "I can probably get you the other three at no charge if you buy the one. Michelin will do that for us, they don't like to put a new tire on a car with the other three worn as much as yours are. I agreed and they re-tired the whole car for $ 300.
Maybe you just need a dealer to go to Pirelli on your behalf? If one won't, another might.

Heterodox opinion: Drive on. That dry rot is very minor and poses zero safety or performance problem. My Pirelli's did the same thing and after four years it was much worse than yours, and I did a track weekend anyway. No trouble at all. Drive and enjoy (but keep your eye on them), and get different tires when the time comes.

Depends how you drive it of course but 10-15 or so. Others will chime in with bigger numbers I'm sure, but my experience is ~10k if you drive it hard and ~15k on average (rears).

Both my 981 and an SLK55 had P-Zeros from the factory. Both rears lasted about 10K (Miles not Km). I no longer own the SLK, upgraded to a 2017 991.2 TTS Cab last year. It also came with P-Zero but they will be changed over to Michelins before next summer. I just went out to the garage and had a close look at the 981’s P-Zeros. The originals are still on that car, they will also be changed out before next summer. Right now all the Sports cars are in winter hibernation mode. The 981 is a 2013 model, tire date codes are all 1713. Other than just over 10K miles of tread wear I see no signs of ‘dry-rot’ like the OPs pictures show. So that car is also a low yearly mileage vechicle, at about 2500.
