Where else but in aviation do you have to pay extra to get inner tubes that
don't leak? You gotta love it.


Bicycling has the same issue. I lose ~40psi a week out of the
tires on my bike. Of course, I'm starting at a much higher pressure.
The tires on my road bike have a recommended pressure of 100psi.
I have upgraded tubes for when I need to replace the existing ones,
but it is easy enough to add air that it isn't worth trashing good
but leaky tubes.
