Silver R/T

What tire psi should I be running in my tires, they're stock size for 01 3/4 ton which is LT2658/75R-16's

There is a tire pressure/load chart on a couple of tire manufacturers web sites. Weigh each axle and go from there. FWIW I run 65 psi on the front tires and 55 in my duels. I get about 120k on the fronts and 100k on the rears with even wear all the way across.

Tire size will be in the door jamb.. my 2001 2500 QC is LT245/75R/16 and 65 in the front, and 60 empty/80 loaded in the rear.

Whatever you run them at you shouldn't exceed the pressure listed on the side of the tire. I have "D" range tires on my truck now for the winter and the manufacturer rates them up to 65psi so I run that front and rear. I don't haul anything that heavy that their D rating will be a problem for me.

Same here on both my trucks.

If you want to get technical draw a chalk or paint stripe across a front and rear tire then take it for short drive on dry pavement.
If the mark wears on the outsides you need more pressure.
If it wears in the middle less.

My tires (previous owner installed them) say no more than 50psi cold, so that is what I run them at. They are Toyo Open Country A/T, LT265/75 - 16.

As atc250r said, you should never exceed what the tire says on the sidewall for cold inflation pressure.

Are you able to read the cold psi ratings on the sidewall of the tires? If so just use that, the tires will have a single load psi rating. If that is worn off, then look in the glove box or the white sticker in the door jam.

pump 'em up to the max tire sidewall pressure cold....
