You cannot use hot tyre pressures unless you also have an electronic pyrometer (surface temperature gauge).
As an example, a 'hot' tyre with 28psi could have started off with 10psi cold but equally so, could have just as easily started off with 14psi. So 'hot' pressures are meaningless.
If you don't have a pyrometer - and know what the ideal opertaing temperature for your brand of tyres is - then you'd be better off (as gozer said) looking at the pressure rise from cold to hot.
