Pete:
I should think that your postcals in general were done at higher temperatures than your precals. Hence tire pressure would be higher and the constant lower. If you remove the postcals from your plot, you may find the temperature dependence disappears.

Also, if you were to fit a pressure gauge to your valve stem for your measurements and adjust for changing pressure,your constant would be indeed constant.
