So, to know the exact pressure at which his tires are inflated, Tom should own a dozen guages, apply them all, and average the results?

Yes, of course. But keep in mind that each time a gauge is used, it causes a tiny bit of air to escape, which results in a tiny pressure loss. So rather than a simple average, it would be wise to plot the results in order, then do a best-fit computation to help account for that gradual pressure loss.

If you want to be accurate, that is. ;-)
