I have a 2005 Ram 1500, 4x4, standard cab short bed. I have LT245/17" sized tires on it, General Grabber TR. Load Range D. Says max PSI 65 cold

I cannot find what the recommended inflation pressure is for this. I'm going to be moving across the country with it, carrying two people and several hundred pounds of cargo. The door sticker says 35psi.. but that was for the factory style tires (20" aluminum rims). I think those were basically car tires, but I may be mistaken

Any recommendations? Thanks!
