correct tire pressure 99 F350 DRW

[rickmondo]

please lend some experience/help on correct tire pressure when trucks loaded with a 5th wheel, 8400 Pds dry?

The door emblem says: 40 psi back and 65 front, but this seems high.
Truck has stock size tires, 235/85-16 E rated

currently tire gauge reads 55-fronts and 50 & 55 back outside tires

Truck is 99 F350 TD DRW Crew cab 4x4 long bed


Thanks much for your help

I ran 75psi in the front and 55psi in the rear loaded with a 13.5k fifth wheel trailer. I got the best tire wear that way.

I always run 85-90. My truck isn't 4wd, but my dad's is ('04CC 4wd f350), and if his aren't at 85 in the front, they look like their flat. on my '01, I've gotten 40K miles on a set, hauling all the time.

65 all around would be fine, but go with what the door says

You should only go with what the door says if your truck is running the same size AND make/model of tire it came with from the factory. If it is not, you need to go by what the tire says.
