The local Toyota place will fill all the tires with nitrogen for $30.
Is it worth it? Thoughts?

Well, consider this - regular old air is 78% nitrogen, 21% oxygen, 1%
other gases and water vapor.

The advantage of nitrogen is that it won't diffuse through the rubber
because the molecule is bigger.

Personally, air is cheaper and mostly nitrogen anyway.

This reminds me of the stories I've *heard* about the gullible going
into a car dealership in the spring to have the "winter" air removed,
and have "summer " air installed in all tires event he spare...


snake oil.

Now, John, if you really want to have something spectacular, take it
to a farm tire dealer and have them filled with Calcium Chloride.

In their tractor tires, the farmers get better traction due to the
increased weight.
