Two days ago when I got in my car in the garage I got a warning that that the tire pressure was low.
The screen said it was 39 psi in all 4 tires.
Yesterday I got the same alert, but as I drove--and the tires warmed up on the road, the tire pressure went up, eventually to 42 psi in all 4 tires, but it was still giving me a yellow triangle with exclamation point alert popping up as I was driving. When I drove back home, the pressure was listed back down to 40, but there was no alert!
The door panel says that I should keep the tires at 42 psi.
It's been cold here in greater Boston the past few days, but not bitter cold, and as the temperature drops and rises, so will the tire pressure (and also football pressure, but I probably shouldn't go there!).
So, given that we've got a few more months of winter cold to go, what's the best strategy for managing my tire pressure?
And what's considered genuinely low, so that if it reaches that value I really need to take care of it quickly?
