Well, according to the nice man at the filling station who helped
with the air compressor,
my tires are all fully inflated and supporting the car nicely, thank you.

THe only trouble is that there is a dashboard light warning that
tire pressure is low and the tires need air NOW.
THis even after a little bit of compressed air was added to each tire.

SO it looks like I have a malfunctioning dashboard light.
All that excitement for nothing.
I'll have to talk to the service/mechanic that fixes my car.
