So I was checking out the camper and getting it ready for the season. Checked tire sidewall for correct psi and here is what it says. Max load 1100 lbs. @ 35 psi cold. Is 35 psi the most air pressure I can put in them? The camper weighs 4,400 lbs. dry. I know a bunch of the weight will be transfered to the truck, but that still does not seem like enough pressure for the tires. It is a dual axle camper with Goodyear Marathons load range B. Thanks in advance for any help!!!!
