What is your opinion about the RVIA recommendation for RV trailer manufacturers to discontinue the use of bias ply ST tires on wheels 14" OD and above?
I've already found one manufacturer (Kenda) that's already building 12" OD radial tires. Boat Trailer haulers are going to like them as they are LRD with 1520# of load capacity.

Interesting, but it doesn't explain why the older trailers also are not experiencing these failures. Nevertheless, the 10% change was something that needed to be done to bring the RV industry in line with cars and trucks.

People complain. "I ran 100 mph while 30 lbs low on pressure and my tire blew out" or "I clipped 17 curbs because I can not drive and then spent 10 miles at speed on the shoulder". One thing is 100$ certain with complaints and that is the complainer is never at fault.

Exaggeration at its best.
I'm a member on several websites that represents most of the non rv type trailers you mention. We see about the same number of ST tire issues as we see on this and other rv trailering websites.
The vast majority of trailer owners (rv and non rv) like their ST tires/brands and have had no issues with them...but many of us have. Most of us found a better tire type or a different brand that eliminated our reoccurring tire issues.
If you feel the need or simply want any ST tire pick one. If you don't feel the need for a different brand or tire type or the added cost of a better tire, no one is going to think badly of you for your decision to keep using what works for you.
NHTSA tire complaints ??
Years back Carlisle had over 180 complaints and Goodyear Marathons lead the pack at 235 complaints. I see NHTSA comes through every so often and removes tire complaints that didn't give the correct info and have in the past removed those that had no bodily injuries listed.
The last 2-3 years we have a better generation of ST tires which brings down complaints. JMO but generally new trailer owners are better educated through forums about ST tire issues as evident trailer mfg offering better tires as a option or come as OEM.
Dead on it's exaggeration at its best, this entire topic. NHTSA "complaints" mean about as much as the spew on this board. People complain. "I ran 100 mph while 30 lbs low on pressure and my tire blew out" or "I clipped 17 curbs because I can not drive and then spent 10 miles at speed on the shoulder". One thing is 100$ certain with complaints and that is the complainer is never at fault.
180 complaints for this or 235 complaints for that, how many actual "recalls"?

…… A hypothetical for the new GY Endurance ST brand could include a collaboration between GY & RVIA. The Endurance came on the market about the same time RVIA made the now enacted recommendation for all member RV trailer manufacturers to provide 10% in load capacity reserves above vehicle certified GAWRs for all tire fitments. ……

…… Yes, the Endurance tire sidewalls have more material than the Marathons. That material is in the form of scuff guard protection and has no bearing on the tire's load carrying ability...…

And yet a LOT of higher end towable manufacturers DO make LTs available... Either standard or as an option. So it seems when price is less important.... That the manufacturers are OK with LTs.
I'm not going to get into the LT vs ST thing. I'll just say this, a high percentage of the industry will not support changing a vehicle manufacturer's certified designated size for a different designated size.

Perhaps I can add something to this thread. Retired tire engineer here.
My expereince with tire failures is that they peak in the third year, but you get a solid, quantifiable, indication in the second year. Also, that tire failures are a summer phenomenon. They are virtually non-existant in Nov, Dec, Jan, and Feb.
The earliest production of the Goodyear Endurance ST tire line is in the tail end of its 3rd summer, and the second summer for the second year of production. I haven't heard of any failures, so my experince says the problems that occurred with the Marathon have been fixed

I had ST tires fail on a popup, a snowmobile trailer and on a utility trailer, but my experience is of no value, right?
