When and if LTs become a significant part of the TT tire market, I predict you will see the same percentage of tire of failures.
Your scenario has already happened.
Before the ST tire came along all we had was a passenger or a truck tire for our trailers (not just RVs). We simply didn't have these type issues.
I don't see our domestic tire makers go back into the tire market just to produce say 13"/14"/15" LT tires for trailers. No more tires that size than they could sell it would be a bust.
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.
Then there is the marketability issue. Example is Michelin recommends the XPS Ribs for commercial trailer application in their old adds.
They don't use that add anymore as marketing says some prospective tire buyers may not want a tire that is advertised for commercial trailer use..... on their expensive 3/4 or one ton truck/burb/large suv/etc.
And yes (for the eagle :)) Michelin still recommends the XPS for commercial trailers and RV trailer use
