It all depends on the weight. Go to a truck stop that has scales and get the weight of your axles. Even better would be to have a four corner weigh. In all the group of manuals that came with your MH should be something from the tire manufacturer. There should be a table in the literature showing the size of your tires and load rating. It should also explain the procedure for determining your air pressure based on your weight.

The sticker calls for 82 psi front and back. I had mine weighed fully loaded with the toad attached and it was over 1000 lb under the stated weight on both axels. I dropped the pressure to 78-80 psi and it sure rides a lot smoother and less wander. Make sure you get the front end aligned and my toe out was not correct and that causes wander. It drives pretty good now. Semis still push it a little when passing
