^^^^^^Ah, that's right. I was mistaken in my interpretation of "all position", I thought they were saying only tires that can be used in "all positions". That's not what they meant though. They meant tires in any position. Doh.
Sorry, I was wrong about how I read the chart. I'm not sure I want to drop down to 70 psi for my tires though. I only have a max of 2500 lbs/tire so I guess I could. Next trip maybe I'll vary the pressures and see what happens to the tire temperatures. If they don't change much then we'll see how it goes.
