The instructor had a pressure guage with him and admonished
me to keep one with me at all times myself.

I have a bicycle pump with a gauge on it in the cargo part of my plane. I
fly to some airports that are unattended and while there may be a self
serve fuel pump, air is not an option.

I check the pressure once a week on my plane. Not unusual to lose 2 pounds
or so in an extended period of idle time, and the bicycle pump takes less
then 15 seconds to get the tire back up to speed.
