Why do bike tires go flat when not in use?

When not in use, tires get deflated over time. This is mainly due to the permeability of the tube and the small size of air molecules. Slowly air molecules find there way through the tube and valve seal. When it is hot the air pressure will be higher and the process goes somewhat quicker.

How full should bike tires feel?

The tires don’t sag down and create a large surface area, because it’s simply not needed. A typical road tire should be inflated to something between 90 and 120 PSI. Mountain bike tires, on the other hand, tend to run at much lower PSI.
