ok, so hows this sound for a quick test.

let the air out of a tire and put a strait edge across the tread on top and pump it up and watch? Not the same as under load, but will demonstrate deformation/psi trend.

I'm still not sure how big of a problem this actually is. I always get the cheap tires and don't have any handling/wear problems to report either at higher pressures (~45psi, ~2500 lb vehicle).
