Even if I use the 2271 lbs of european tires as maxload , my spreadsheet gives 64 psi.
This is maximum reserve without bumping.
So if you used 65 psi , I cant explain the falling apart by to high pressure. So not what I expected.
Or it must be that you dont load it to the max of 4475 lbs.
If I would have used the 2040 lbs maxload given for your ST, my pressure-advice would have come even higher, even 72 psi.
