if know the what the temp is going to change to can i know what the pressure will be?

 

Too many variables. One reason N2 is used nowadays is to eliminate moisture, which is affected different than dry air or N2

The size of the tires, type, bias, radial, steel, etc, even the type of wheel. Aluminum wheels will conduct more heat away from the tire than do steel, so even the width of the wheel comes into play.

Only way I'd know is to make a few measurements at different temperatures so you can check it. I mean, if there was an easy way, would racers need pressure gauges?
