By the way, I also agree with what Glenn had to say. Under or over inflation of tires are both bad things.
My prior post was only to post additional info, not to disagree with what he had to say.
My point was that the Mission tires have a higher load rating than the tires previously installed on the Monty's, so thus do not need to be inflated to the same 80 PSI in order to support the weight.
And yes, my Missions are load rated E (10 ply). I'm guessing that all other Mission tires installed on the Montys are also E rated.
