How about this that I learned from the Dodge Dakota newsgroup a while
back? Forget about tire pressure for now. Load up the plane to what
you expect to be the normal operating weight. Pump up the tire untill
you get full tread and no sidewall contact. Take the tire pressure and
use that from then on.

How do you know when you've got full tread contact? Pour some water
just in front of the tire and pull the plane through it, letting the
wheel turn completely over a couple of times. It'll leave an 'imprint'
on the second time around that will be a mirror image of the tread
pattern. If you can read sidewall numbers, you need more air. If it is
just a thin strip, you need to remove some.
