Nowadays pressure advice is more for reasons of responcibility. In earlyer days it was calculated for the expected axle-weight and speed, but sometimes proved to be to to low because of overweigt and or unequal weight R/L.
Thying to find a balance in this , different advices are given. Also advice now is kept high, wich can give discomfort and bad gripp.

I once got hold of the official european formula and went running with it. Now call myself " pigheaded Dutch selfdeclared tyrepressure-specialist".

32psi as per recommendation sticker on right door. cold tyre pressure when the Car is driven less than 3-5 kms...

What should be the pressure on a hot tire? Say after a vehicle has been driven a 100 kms on a hot day?

After driving about 90km/55m /h long enaugh the temp in tire will rise to about 45degr C. / 110degr in tire , when outside 18 degr C/65degr F .
This will rise the pressure about 10%.
On hot days so the inside tire will rise more, but not lineair , because more pressure means less deflection so lesser heatproduction.
And when you measure when tanking, how far has it cooled down. For this reason cold pressure is always reliable.
Cold means when inside tire temp =outside tire temp. And then pressure advice is for when outside tire temp is 18 degr C/ 65 degr F.
So if tou want to be precise, calc back pressure to temp 18/65.
