Michelin XPS Rib at one time ran this add on their website but was later dropped . I had two Michelin truck tire dealers say that Michelin said they felt some prospective XPS Rib buyers may not want a tire on their high cost truck/van/suv that says its for a trailer.
**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.

ST tires are a niche tire with low national sales. The major tire makers mfg their own ST tires at one time years ago. There simply wasn't big money in the niche tire market like the ST or agriculture tires/construction equipment tires/etc.
LT vs ST production numbers...... rvtiresafety.com
In 2014 there were about 310,000 trailer sales. A majority of these came with ST type tires and some with LT type tires. While I could not find specific figures I believe that almost all ST type tires were imports. I would estimate this represents almost 1 Mil. OE tire sales.
In the US there were about 7.6 Mil cars and 8.7 Mil light trucks and 400 thousand heavy trucks produced in 2014. There were about 253 Mil. passenger tires plus 33.6 Mil. LT tires and 23.1 MIl medium and heavy truck tires sold at replacement and OE.
