I have getting quite bad gas mileage lately, and I believe the reason is because of my tire pressure on my 31x10.5 is a bit off. I looked online and on the tire and couldnt find where it said what i should be at, so if anyone could clue me in on what the proper pressure should be that would be excellent. Btw I have 31x10.5 BFG A/T KO's.

Thanks, Derek
