Inside the drivers door panel it says 35 so I usually run a couple higher, that's just me.

you should run them lower,say around 30-32 and keep an eye on how they wear. 35 is at max and thats when your carry a full load. anything higher and you'd be wearing out the center tread.

35 psi is for the stock POS tires that come on the truck....BFG's are 50 psi if I remember right.

it depends what you want. better gas mileage/rougher ride, higher psi. worse mileage/softer ride, lower psi. an easy way to figure out a decent psi is to make a chalk line across the tread of a tire, then get in a drive a few feet and see where the chalk has worn off. regulate air pressure until you get an even wear of the chalk line.

I was running Cooper STT's at 50 psi, no wear problems, and got 19mpg outta my durango consistently. Gave them up in the trade for my 04 screw. They wouldn't have fit anyway. (best off-road tire i ever had, too)

Thanks guy's. When I had them put on the tire place put 50 psi in the BFG 285 65 18. Truck rode like it had solid tires. Dropped them to 45 psi. Rides better no difference in the positive steering these tires exhibit. A co worker has an FX4 S Crew and he runs 40 psi. He say's it's his second set and has gotten 80 k on both set's at
this pressure. My truck is a Super Cab and I haul more tools than he does so I fugured 45 would be good. I will do the chalk trick and see how that pans out at
45 psi and go from there. I welcome any more info on this and I will let y'all know
what I come up with. Thanks for all the replies.
