Since I switched from asphalt to dirt, this has been bothering me. On left side tires, I run pretty low, like 8 and 10 (front to back). But, my tire temps, specifically in the LF, show that the tire is under inflated. The right side tires go through too much "stress" to really get a good tire temp reading. So, I don't know how low is too low. I'm just asking, what advantages are there to running low pressures, even though the temps will show it's not using all of the tread?

On dirt the LF does hardly any work, as you know. 8 lbs is a common number for that tire, and I would concern yourself with using whatever air pressure gives you the best response out of that wheel. One thing that I ran into when I first started taking temp readings was uneven temps across the LF with the inside of the tire always running hotter than the rest. At first I thought that it might be a camber thing, but somebody pointed out to me that the brake was heating up that side of the tire, and I would get that sort of reading. If there is a few deg differance between the middle and the outside, with more on the inside then this is probably the case with yours.
