I don't know how to combine Boyle's law and Avogardo's law anymore. I cannot answer your question.
But practically. Cold tyre reads lower pressure at the gauges. Lower pressure takes longer to heat up. The road tyres will have the best grip when it is slightly heated, but not overheated - for the exact temperature is different for different tyres. Does manufacturers give those details?

has anyone tried nitrogen inflation? it supposed to keep the constant tyre pressure and better fuel economy for long distance trips. the normal air we pump from servos contains water (cant remember the percentage...)
have done it to one of my previous cars.... didnt keep it long enough to notice the difference.
