Long story short I caused a lot of trouble saying I ran my MTR/Ks at 14 psi. I just got them and that's what the chalk test said to run them at. Gave me full tread contact across the tires. I was then informed the chalk test is not the best tool to use with big tires on proportionally small wheels. OK. So I ran my tires at the PSI range that was suggested to me. (20-24 psi) This picture was with 20 PSI.
Well I just got back from a little light wheeling got some mud on the tires and made an interesting observation. The tires are only contacting on the center as I feared form the start. See:

I think it's pretty safe to say forget the chalk test and just run them in the low/mid twenties... 22-24 and you'll be fine. YJ's are not that heavy and when running meats in the 33-35 flavor on your average 8" rim, that is about the right psi. Off road, drop 'em down to whatever you like. .o2
