Tire psi

I have a 88 f350 4x4 crewcab SRW longbed riding 35x12.5/17. I basically just use it to get around town, to and from work, and once or twice a month pull my 4 horse trailer. Every once and a while hit a trail in the Everglades here in Florida but nothing ruff or deep mud. What kind of tire pressure should I run in my tires??? Again they are procomp tires 35x12.5/17.
Thanks in advance.

Get some chalk markers, and make a big fat line across the tread of the tire.

Drive over that line a couple of tire rotations, and see where the line is mostly faded. Keep trying that until you find the correct PSI where your tires will wear down nice and flat.


Just a reminder, wear in the middle of tread is to much air - wear on the outside edges, not enough air.
