I am trying to make sure that my tire pressures are safe to drive on for our first trip until I can get to a facility where I can weigh my coach. There isn't one nearby and I don't want to drive 100 miles, roundtrip, just to weigh my coach before our first camping trip in the motorhome.
Please let me know if I am doing this correct and share any information you might have:
Coach: 2002 Monaco gasser, 37 feet, 2 slides. My wife, myself, and two small children. We don't have much packed because this is our first trip, and there is currently NO water in our holding tank or black tanks.
GVWR (22000), GAWRfront (8000), GAWRRear (14500)
Tires are new Michelin XRV 235/80 R22.5, no tag axle.
According to this chart
my tires should be inflated to 85 lbs in the front and 85 in the rear if the coach is fully loaded to the Gross Axle Weight Rating. There is no way we are loaded that much, because if we were then I would never be able to carry water or lots of food, or when my kids get older and are heavier we wouldn't be able to have them with us. Now, I won't have exact
values until I weigh the coach on all 4 corners, but can't I make a reasonable assumption that I can safely drive this coach an hour away to the state park with my tires inflated to 80-85 lbs in the front and rear?
Does this sound right? Am I missing something?
