Even clicking on Michelin load and inflation tables for RV tires , it still comes up with the XPS Rib tires .
These are NOT the Michelin tires we are running , most are running the Michelin Defender or LTX tires.
Wonder if the tire pressure rating is the same ?
If it's the same basic tire classification and size and load range (classification as in "light truck" or LT tires), then the chart will be the same, or close enough for all practical purposes. That's also true across brands, incidentally. The only exception I've seen is a few tires that allow higher pressures than standard and so have the chart extended a bit more...but usually the Ford (and I suspect Chevy) stock wheels are not rated for more than 80 psi anyhow, so it's rather a moot point for most class C motorhomes.
