But isn't that PSI on the car's door jamb for the tires that came with the car originally? If you change tire types such as going to low profile tires, the recommended pressure is now different for those tires.
So blindly using the door jamb values is not always the correct approach for every time and rim you put on a car. If it was, then you could swap out all four tires and replace them with temporary run-flat spare tires which may have PSI up to 60 since they are special. BUT, no, you cannot use 60 because your door jamb says 30 PSI. Hmmmm.
That's why you should keep track of the recommended tire pressure for those tires when you purchased them. Since, tires have the PSI value stamped on their sidewall, look there first instead of just using the door jamb/driver manual values. The PSI value on the tire sidewall must be the correct pressure since the manufacturer put it there for that specific tire.

>max psi is operating pressure
This has to be bait.

This is so wrong it physically hurts my brain to read it.

Find a middle ground.
> In my case Toyota '03 Camry 29 PSI recommended for all. Tires max PSI 51 29 far too little to comfortably steer vehicle Found out 36 PSI is perfect.

Run them at 25psi. Max PSI on the tire is for maximum carrying capacity. The recommendation in the owner's manual is for a full load of passengers and cargo.
Lower PSI = more flex in the sidewall and a more comfy ride.
Also when you fill them up too high it makes the car hard to control. Look at Russian dash cam videos. You see how the cars can just lose control for no reason? It's because they run 65psi tires.

Lower PSI also means more grip because of a larger contact patch. More manufacturers are recommending lower PSIs nowadays for muh safety.

the door door plaque only apply to the original sizes of tire and wheel
if your current set are lower profile or a different size on front and rear axle they will need different setting

I have 8 bar of pressure in my tires, makes them nice to drive on.
