Confused a bit about tire psi. The label on the outside of our Tab 400 states 50psi but the tires are listed at a maximum of 65psi with associated payload (see photo) and that's what the dealer inflated them to (or nuCamp did) before delivery. What should I inflate them to? If I take out air and reduce to 50psi will that reduce my payload/total weight capacity to potentially some dangerous level? We drove our unit home with no issues but as we get ready for our maiden voyage I would like to make sure we are riding safely.
