For tire pressure, you are supposed to reference the CAR MANUFACTURERS SPECS (usually inside a door jam), not the specs listed on the tire.
What if you bought a none oem tire?
I tend to look at the tire wear as a basis for my tire inflation. I also tend to stay on the overinflated side.
I skimmed the thread, but surprised no one listed nitrogen? Seems like a gimic to me but.... Nitrogen gas is less affected by temp changes, it also is a "thicker" molecule and less likely to seep out of a tire(not talking about a leak).
That said I still think its a gimic in cars.
But I also think most people in this thread are a bit over reacting o. The higher tire pressures.

If you buy a Oem or non-Oem tire........they should still fall within the manufacturers specs for air pressure. If not.........well, in some instances you may be asking for trouble.
a 10 psi swing isn't good for the tire or the economy. Why not just fill it to 35 psi, like the (assumed) auto manufacturer states is proper for the vehicle?
Why not just do it right, without all the silly "strategy"?
Because it's impossible to do it right unless than an acceptable deviation from the optimal value is specified. Why 35 psi and not 36 psi? or 34 psi? or 34.1 psi? Is a 1 psi deviation acceptable? 5 psi? Not enough information.
If the non oem tire is of the same size and load range as the oem tire then the psi listed for the vehicle can be fallowed.
But if the tire is not the same size or load range
you might think so but they don't.
When you put on some larger or smaler tires or a different load range you will need to find what the "new" psi will be.
You can do a contact test.
You can do this in various ways.
Using chalk or water etc etc.
Over inflated and only the center of the tire will be making contact with the road, under inflated and only the sides of the tread will make contact.
Then watch how your tires are wearing. Adjust psi accordingly.
The MFG has done the homework for you and has listed the proper psi for the weight if the vehicle and the "oem" tire that is being used.

If you work from the position that no deviation is acceptable, then it's easy to do it right. This isn't brain surgery. Check the pressure monthly at least, and if it's off, adjust as necessary.
I manage to keep mine within +-2 psi by checking a couple times a month. Allowing a 10 psi swing implies one knows it's happening, but chooses to not do anything about it. It's a silly system. That 10 psi swing means the pressure is almost always incorrect. Does that make any sense?
I refuse to accept any excuses why people cannot perform (or have it performed if they're truly unable to do it themselves) this simple task as often as needed. The anecdotal reasons in this thread being used as excuses for not keeping the pressure correct are just silly.
In keeping with the modern American penchant for "being into" things rather than simply doing them we now have people who are "into" tire inflation. Cool.

How hard is it.........you are not supposed to use a TIRE that does not fall into the specs spelled out by the CAR MANUFACTURER.

I agree its best to see how the tires are wearing and adjust for your needs.
Yes the manufacturer did do their homework. But they didn't do homework for my conditions.
They generally design something that meets northeast snow, and southwest heat, and southeast rains... All on the same tire. In FL I bought nothing but summer only rubber, we get below freezing in SC and its funny the summer tires on m
G6 will have a flatspot and "wip" until they warm up and reform. But they are summer tires.
My camaro is a bearer, tires are old I just keep them inflated on the high side.
When I raced I had a slew of tire pressures for dragracing and autocrossing and street driving.
