The Nissan Path

Was drivng ym care and the pressure tracking in center stack told me pressures were down due to the cold but not so much to set off an alarm.
Drove like this for a week ( since he cold started here)
Today finally pumped them back up just 3-4 psi depending on individual tire.

The car really feels like it just got woken up.
Much more spry handling from just a very few psi!

Any stunt driver can tell you that even a '69 DeVille will handle with 80 psi in the tires.

Added a couple ,more PSI as it got colder.
Car had to drive 200 miles round trip with a load NOrth
So I pumped it to 37 cold.

I am spo happy I did that.
air along the road is often expensive and cumbersome to use but i am lucky at my work we have a free airpump where you just punch in the numbers and it stops when it gets there.
