you forget i have very little weight on the back of my truck.

fuel mileage is a joke for me, i get 8 or 9 on the highway so i go for full contact patch.. and for my entire tread width to touch the ground on my rear tires they've gotta be low.

i keep 32 up front and 28 in the rear. 32 psi up front b/c all the weight is in the front. If i haul something, ill go up to 32 psi in the back as well.

That's great if you're running stock tires as listed on that sticker. For those running aftermarket tires other then what's listed, you can forget about what that says.

I try to stick with 34psi in my 31x10.5 BFG A/T's

my oen 33's work well at 32 PSI for a godo contact and good wear.. I do pretty much most of my driving on that - if I hit the powerline roads, I usually air it down to about 20-24ish

35 on the highway, 10-15 offroad. Anything more is just going to inflate the center of the tread and cause premature wear in that area. Also your truck is going to ride like a brick lol.
