what should i run for pressure on my stock 265's to get the best mpg....thanks

also, if i switched to 285's....will the mpg go down and will the dealer recalibrate the truck to that size?

I run 70psi all the way around on my truck. MPG's are good and the ride is fine in my truck. They were at 45psi from the dealership and they seemed too soft and squishy. Scotty

Per DC, 55 front unloaded, 65 front loaded, 40 rear unloaded(or higher if yo ucan handle the ride) 75 rear loaded.
You should have received a Tire Inflation guide with the truck, if yo didn't then look to see if they updated the drivers door panel and then if not go smack the dealer to get you one.

I run 55 psi all the way around empty and rotate every 10k miles. So far all the tires look great (26k miles) and it does not ride like a tank. When towing the 5th wheel I run 60 psi front and 70 psi rear.

Mine came with 50psi all around. I tried 70psi front and 65psi rear for a while. The ride did get a little stiff. Now I run 66psi all around (66 is easier to read on my gauge that 65 is). I have no complaints.

One time, I forgot to drop the pressure after a towing trip. Had the rears up to about 80 lbs. & the fronts at about 70/75lbs.

Late one afternoon, the sun was low but bright. I could see the sunlight underneath the outer edges of the tires, especially, the rears. That would have caused premature inside tread wear. I, also, have a 115 gal. auxillary fuel tank in the bed which adds close to 800/900lbs to the rear.

I have since dropped the pressure to 65 all around & get no more sunlight under the outer edges of the tires. The tread sits flat on the ground.

The truck & tires have 48,000 miles on them. The wear is very even. I have not rotated the tires as often as I should but, do it occasionally. Recently, I got a small screw in one of the tires. Took it to a local tire store & pulled the screw out. No leak. The tire guy checked the wear & said there still was 40% wear left on them. These are the BFG Rugged Trails that came with the truck.

70 front, 65 back....

Do you want long tire life or higher mpg? I've tried various combinations of tire pressures. Typically 55psi empty. When loaded 65psi front/75psi rear.
