Fill them with Nitrogen they won't leak as much. Not that I've tried it.
How do you figure that? Air is already mostly nitrogen. Why would a
higher concentration of nitrogen leak any less than plain old air? The
difference in atom sizes between nitrogen and the other major constituents
of air is on the order of a few percent, so even the other constituents
aren't going to leak out leaving just nitrogen.

And, that few percent difference makes a small fraction of a percent
difference in how fast they leak. Not enough to notice, but enough that tire
stores around here (Detroit) make all kinds of wild claims about the
advantages of buying tires from them and having them filled with N2...
