What size are the g rated tires on toy haulers

[rtaylor0830]

Does anyone know what are the sizes of the 16 inch g rated tires on most toy haulers now

Kinda what tireman9 says in his rv tire safety blog where he talks with a TRA engineer about the need for ST tires to have their capacity reduced up to 25%.
Tireman9 says;

**Finally chased down the answer. Getting to the bottom was a challenge because I ran into "customer service" people who could read from a script but had no idea why they were giving me the answer they were.

Even got to an engineer at Tire & Rim Association and based on his answers it was obvious TRA had not thought about ST type tires or the unique nature of most RV trailer applications for many years so I believe he acted a little surprised when I identified the engineering analysis that indicated that the current loads too high for many trailers and that the load capacity should be decreased by 15% to 25% or more if the failure rate was to be decreased to a more tolerable rate rather than the 5 or 10% or higher some are reporting. This is not his or TRA fault as I understand it is the responsibility of tire company representatives to TRA to present and review technical matters.**

You might drop over on Tireman9 and ask him your questions.

You're right maybe I'm just the lazy one. My cursory search didn't turn up anything.

Taken I took an educated guess,but I was hoping to do better than my speculation. I was hoping that someone with more official knowledge could confirm or refute my speculation.
Have the ST vs. LT criteria become some sort of secret that can't be discussed?
Has it become a taboo discussion for fear of locking the thread.
Funny there is already one pre-locked thread out there already.

More importantly what if my speculation is wrong? I hate to spread misinformation. There plenty of fake news already without adding the ST vs.LT ratings to the fray.
It's a simple question, why is the ST load rating higher than the LT load rating assuming we are referring to the exact same tire and it is only a ST.vs. LT ratings change due to taxes and tariffs?
Anyone else care to speculate.

The Sailun's were actually LT rated until a couple years ago. LT tires have a higher import tax than ST so Sailun kept the tires the same but changed the designation to ST.

I bought the Sailun when they were designated as LT tires, and their weight rating was 3750 lbs.

Yes I have LT rated stamped tires as well. I have been told they are the exact same tire as the ST version which I don't dispute.
However now the load rating has increased to 4000+#on the ST stamped tires. How or why did the rating change if it is the same tire?

I have no idea what tires most TH on a rv website use but G Tires above seem the most popular with operators on haulers forums.

Sort of unrelated but I'll use the above post for reference.
Do LT (passenger rated tires) require more margin in their load ratings and consequently aren't rated as high as the ST tire.?
Can anyone verify this?
Note the ST's are rated to carry more than the LT's listed above.
