All fingers should be pointed at the DOT. I’ve spent many hours searching for studies that describe the dynamics of the RV trailer and the effects that may differ from tire usage on other vehicles. It cannot be found. The RV trailer can be 13’ tall, more than 8’ wide and more than 43’ long. They can have single, dual, or triple axles with combined loads exceeding 20000# on the axles. The axles (more than one) are almost always close together and cannot be sharing the total loads equally.
With few exceptions the Special Trailer (ST) tire endures the wrath.
On the few trailers with 8000# axles or larger, the low platform truck trailer tires are performing well. They also have oodles of excess load capacity.
In my opinion, the OE tire failure percentages will not decrease until the DOT steps in and, in some way, patches-up the loop-holes in the existing regulations for RV trailer tires.

ST tires endure the wrath of horse trailers and boat trailers owners also. Send them back to small utility trailers where they started! Problems will be a lot less. I am sure that the height of 5th wheels puts extra loading on the tires, but how do you explain the failures on all the other trailer types, other than the overall quality and lack of necessary construction of ST
LT and commercial truck tires seem to able handle these conditions much better than the light weight ST tires.
I am sold on the steel carcass offerings for this kind of service. If I had a larger trailer it would be on 17.5" rims and LRH commercial tires. Knowledgeable manufacturers and consumers are making the transition to such wheels and tires.

I am going to quote myself! Is it not time to write 60 Minutes or 20-20? As the problems are not life threatening as pointed out above!
The one person on here that maybe knows how far spread the issue really is, is FE. He is on forums of all kinds under several users names across the net trying to defend the failures of ST tires.
I will repeat, this issue is not related to just ST tires on large 5th wheel trailers. Trailers of all types have experienced the same issue with ST tires form just about all manufacturers.
We go around and around on this forum on this issue repeatedly. The fact still remains that failures repeat until an user installs a high quality LT or switches to 17.5 rims and commercial tires on the larger units.
NuWa seems like a leader in the 17.5 rim/tire conversion, even helping it's customers with the purchase of the rims and tires.
I commend the mod of this tech issues forum for letting the issue get really discussed, however nothing has changed!
The surest way to resolve ST tire failures is to get off of them!
