Our Mada came from the dealer with the stock tires at 44 PSI. Although this seems to jive with the suggested PSI on the door, it seems a little high for our lifestyle. We aren't towing anything except 4 kids who weigh 200lbs when piled on top of each other. I had always run our Surburban around 38 PSI, with good tire wear, and I'm thinking about doing the same with the "Beast". What is your experience?
