The lowest temp was -2F (-19C). The other time it was about -17F (-8C).

First car? Or first time leaving San Diego?
Seriously, you have to monitor tire pressure in changing temperatures. This even includes spring, as you don't want overinflated tires due to warming.
Ever check a suitcase on an airplane and have a sealed plastic container inside that had some air in it? Notice the difference when you arrived? Two things will change the pressure of the air - temperature and altitude. When either changes significantly from when the tires were inflated, you need to check them and adjust accordingly.
