Gil, ok you convinced me to keep the pressure where it is at. Pressures are about 10 psi more than the Michelin chart calls for to compensate for any errors in the weights since I did an axle weigh rather than a four point weigh. I understand the importance of a four point weigh. I had a new 2000 country coach intrigue with one slide and there was a 1500 lbs difference between the driver side and the passenger side. This was a major problem on motor homes with slides and cost CC a lot of money to replace tires and change front end design.
