"Sarcastic?"
Who, me...?
Nahhhhh ... I just get a little perturbed when lawyers make life more difficult than it needs to be.
(my apologies to any Yota lawyers out there. You're OK. It's the Beemer-driving ones who piss me off.)

OK, here's the promised report on tire pressures for the Goodyear Wrangler AT/Ss on my '99 'Runner ...
I drew a line 1/4" in from the edge of a business card and slid it under the edge of the tread of the front tires (from the side.) It went in nearly to the edge, indicating that it could use still MORE air to fully insert the card to the 1/4" mark. They already have 50 psi.
When I tried the same measurement with the rears, the card went in waaaay past the mark, indicating that the tires had too much air in them and needed to be deflated some.
I let air out until there was only 27psi and I could STILL pass the card farther in than the mark! Since the initial problem was the squirrely feel of the new tires (presumably from underinflation), I wasn't about to have them inflated LESS than Toyota's recommended 32psi.
Therefore, my faith in this form of pressure measurement is shaky. Maybe it's the type of tire. Maybe I didn't do it right, I don't know. But I went back to 50psi and will keep them there for road travel until I hear something authoritative or start seeing bad tread wear patterns.
End of saga.

I understand that, but TWICE the pressure?? I've traditionally carried a couple of pounds more pressure in the front because of the extra weight, but not THAT much.
I'm wondering just how much I'd have to deflate to make that 1/4" mark technique work. I may play with it again, but when it fell below the recommended pressure it didn't make any sense to keep on deflating.

just run 0 and run on the rim. 
I still need to do the test on mine and inflate accordingly so I'll let you know what I find. probably will wait until thanksgiving because I'll be tearing my steering rack apart and replacing the bushing stuff on the drivers side.
