How Much to Air Down??

All,

It's finally getting warm enough to take my truck out and hit the trails. I recently put some respectable tires (BFG KO2 265/75/r16) on my truck and want to hit more difficult areas of Southern Idaho.

I know airing down is the name of the game, I'm just not sure how much??

So my question is.... how much do you air down? And is it tire size dependent? Trail surface/obstacle dependent?

like always, Thanks for the help!

 

For my go to wheeling pressure, I air down to 15psi. If I’m going to be doing less technical stuff and going faster (ie a bumpy fire road) I’ll air down to 20 psi for comfort. This is assuming your tires are load E
