I hope you realize that these so called 50 psi tires could have been labeled 35 psi tires. That's because of the "notes on page 1-34".
I discuss that about 1/3 of the way down:
Barry's Tire Tech
The 50 psi is a permissble usage - and it should be obvious that the intended use for this pressure is high speed operations - and when tires are tested to those conditions, it is in the context of high speed operation.
But when vehicle manufacturers are specifying inflation pressures, they are in the range of 26 to 35 psi - at least in the US. In that context,it doesn't make a lot of sense to test outside that range - particularly given that this is the design standard and not some usage table.
