PSI for new to me truck

[septanker]

My 2011 F350 6.7 has Toyo M/T Open Country 35/12.50/18 LT Load Range E tires on it. What PSI should I have in them? The sidewall says that full loaded cold psi is 65. I am thinking of running 60psi in them for day to day driving. When I pull it will be a Toyhualer at a loaded weight of about 9000lbs. Thanks

Proper Tire Inflation

when towing I go full sidewall marked psi

I ran open county all terrains lr E for years. I kept them at 70psi. I think the sidewall said 80.??

Off topic but do you plan on towing with those tires? Mine didn't last and at the price of Toyo's its disgusting.

I do plan on towing. They came on the truck when I bought it on Friday. Now they look bada-- but when the go I will put a good towing tire on. I read the side wall of mine as 65psi cold for a max load on them, so I have 62psi in themnow. My camper is 9000lbs loaded to the gills. I looked them up online dam- things are like 350 bucks each. Maybe I should sell em. They are on the stock ford 18's
