Tire Air Pressure
I know I've read it here before about front and rear tire inflation door sticker calls for 75 psi i have LT265/70R17E All Terain BFG's i think i read 50psi in the rear with no load and 55psi in the front because of more weight,any info will help

I am running 315/70/17 BFG A/T's (have had 315's for years), and I have been running about 50-55 in all four for year. Never had any problems, and I usually get 70k+ miles per set. I do not haul heavy loads on a regular basis though either. I do plow, and tow the occassional trailer, but no massive loads in the bed.

I'm running the same 265/70R17E tires on my truck (see sig).
75 pounds all around gives a bouncy ride.
70 PSI all around rides good.
If I go 65 PSI or lower i start getting a death wobble in my front end )steering wheel oscillation) after hitting a bump.
You may or may not find out this is true with your rig, but you need to experiment to find the best pressure for your situation.

I have the original equipment BFG's on my dually. The truck works real hard but is very rarely off pavement. I forgot what the inflation pressure is but it is the max cold as stated on the tires. Yeah, it rides a little on the stiff side empty, but it is rarely empty so I don't notice.
I've been told that airing them up high improves tire life. I can't tell for sure since my BFG's only have 112,000 miles on them. As soon as they need replacing, I think I'll keep the replacements aired up pretty hard also.
