air pressure is measured in psi (pounds per square inch) so size or tyre is kinda immaterial. the pressure to be maintained in the tyre remains the same.
that said you are right when you say manufacturers specs are redundant with after market tyres (stock size or not) because manufacturers take into consideration the tyre compound in various conditions and many other variables before they come up with recommended tyre pressure.
