I'm assuming you are talking about the tow vehicle pressures. While I haven't weighed this van nor my current trailer, I am aware that the manufacturer of my tow vehicle has a recommend tire pressure on the driver's side door. Being one who brings along other items including the trailer, the load in the van not only includes the obvious hitch weight, but its passengers, grill, a full fuel tank, possibly Patty's electric cart, just to name some of the things.
Bottom line I want the van to be at its rated cargo capacity specs, so the answer to your question is yes, I check the tow vehicle tires before each trip and bring them up to manufacturers specs prior. I've never done wrong doing it that way and I have a high degree of comfort level when I hit the road.
