I seem to recall that the findings involving Ford Explorers rolling over and playing dead on Firestone tires were because of under-inflation; people airing down to get a better ride. We're talking about trucks and 4Runners here. If you can't handle a rough ride buy a sedan.
As for me, I run mine at 50psi.

Bingo.
When I put on new tires, I just watch as the nubs wear off. Adjust until the tread surface wears evenly.
Note that on really big tires this isn't really possible. My 35s would need to be at about 12 pounds to get even wear. Rides like an old Honda 3 wheeler (bouncy bouncy mushy bouncy) at that kind of pressure, plus consumes gas like crazy. Rides the best at about 40, but then wears out the center of the tread face really fast. So I compromise, and rotate often.
