Michelin Introduces New RV Tire Site

I challenge you to find it listed on the page you posted. I use
XPS ribbed, but they don't list for TRAILER anywhere that I can find.

.....Michelin ran this add for many years;

Michelin® XPS Rib® tires are the best value per mile in the Michelin commercial tire lineup and an ideal choice for commercial trailers because of low rolling resistance (for better fuel economy), a long-wear tread design and retreadability. These tires also have the strength of a reinforced all-steel construction for lasting durability.
