We get a bit below freezing a few times each year, but there's a huge gap between 29 F and 9 F ...Yup, it's always an adjustment when you are not used to it.
We are up to -14 today and it's a nice change after the deep freeze we just came out of. Suddenly it is so easy to heat the house.
I was taught to check tire pressure any time we had a cold snap. To be honest, this happened in November, so I only had to check once per year, until it warmed up in April.When did air start behaving this way. Before my vehicles started monitoring the pressure in my tires I never added air in the winter.
We checked my f-in-l's vehicle -- normal pressure is 35 PSI, he was down to 27-29 PSI in all tires.
