Air pressure help

I have P285 75 16 Toyo MT's . I got the tires at my local Ford dealer and they put 35 pounds of air in them. I'm thinking that was not enough. The side wall on the tire has a max of 80 pounds. The 35 was for the original tires. I am running 65 pounds and wondering if this would be o.k. They seem to be wearing good, i rotate every 3,000 miles. What do you all run in this size of tire. I have searched the site and can't really find a answer. Suggestions?

I just put on 265 75 16 - Max PSI is 80 and the tire shop told me to run 65.
Some people on here tell me no, run 35 for a smooth ride. But i found a nice in the middle at 50. Seems ride, wear and gas mileage is doing good. But i have no real miles to speak of yet. about 1000.

Technically you are supposed to run what your truck says. But a little bit higher can be good, 60 is way too much for a ranger. Rough ride.

You follow the info on the tire concerning proper PSI. That's what I've always done. I'd only follow the Rangers specs if you stick with factory size and similar brand (ply) of tires.

My father runs 52psi in ALL of his tires regardless of what they say and he's always got more mileage out of his tires than anyone we've ever known. Considering we have a good 50 tires in use at any given time here on the farm, I'd be inclined to trust his judgement.
