I did a google search using "inflation table for MICHELIN XZA1 tire", and got several inflation tables, but nothing in your size for xza1.

Hi rally tally,
Welcome to iRV2. I have the same size tires as you. I did not know Michelin made a load range "H" in this size. My tires area load range "L". Go to:
Michelin North America RV Load & Inflation Tables to see the Michelin table for this size tire, but different load rating. You'll need to scroll down the page to find the right size.

GaryKD is 100% correct. Also you should wiegh your coach in a loaded manner as it would be when traveling. Fuel, fresh water, and all else, once you do this the inflation guide will give you proper pressures. Don't just run max pressure unless you enjoy a harsh ride and accelerated wear in the center of the tire.

After you get the recommended pressure and if you want even more exact results, use the chalk line trick.

Method. . . . Draw a line across your tires when they are at operating temperature. Now drive down the road five or ten miles or so, stop and check the chalk lines you drew.

If there is still chalk on the edges of the tire, you are overinflated.

If there is still chalk just on the center portion of the tire, you are under inflated.

If the chalk is all gone CONGRATULATIONS, your tire pressure is just right.

Actually, I draw three lines per tire, one on top, and one on both front and rear. This assures ease of sight of at least one of the lines when stopped to check the lines.
