Why on earth do you need to change the air in your tires before a trip.
It is always a good idea to check your air pressure and inflate tires to
the recommended pressure.

Something to thing about.... and maybe I should patent this idea. Air
leaks over time. Rubber is a pretty good sealant but the gas molecules
still manage to seep through the material, so the pressure eventually
drops. The reason for inflating tires with nitrogen is that the
molecules are larger and less likely to work their way through the those
tiny gaps.

Now..... If there is truth to that and you pump regular air into the
tires, and the other gases leak out, the gas left in the tires should
have a higher percentage of nitrogen. Nitrogen makes up 78% of our
atmosphere. Every time you add air you are loading air that it mostly
nitrogen into an already nitrogen enriched vessel. Eventually, it is
going to be almost 100% nitrogen.


Personally, I figure that the simple practice of checking tire pressure
and keeping them at the proper inflation will give you the same
performance and mileage benefits that you might expect from nitrogen,
but without the hassle and expense of having to fill them with nitogen.
