RV'ers seem to be mislead on proper tire inflation pressure. I have been accused of trying to act like an expert on this. I have found a video by Michlen tires that explains how to weight the rig and use a load and inflation table for PROPER inflation of the rigs tires. So it is no longer my experience and opinion, it is by Michlen who may just be experts on tires.
I do not much care what Randy the RV guru said, I will listen to Michlen. They also have a couple good videos on RV blowouts.
