The following has no earth shattering revelations, just some interesting info (to me) I've picked up in the last couple of days.

After a couple of posts on the forum (I believe it was this one) about a Sailun load inflation chart I thought I would ask "Sailun" for one (gosailun.com). Well that website is actually TBC Distributors which distributes Sailun and other "value tiered" tires. Their response was that the tire pressure required in the tire was on the placard on the trailer determined by the RV manufacturer but gave me a little chart for the 235x80r16 as sort of a good will gesture. If I needed any further info on the tire I was to contact the RV manufacturer? I had to question that.

I told them that the RV company doesn't make the tires nor make load charts for them; that would come from the tire manufacturer. If, as I did, you go up a load range supporting the same load that was placed on the OEM tires, then yes, a load chart is beneficial to the owner of one of "their" tires. Since that has to come from the tire manufacturer please guide me to their website to get those answers if they didn't have them as I've never found a direct contact with any Chinese tire manufacturer. Today I got another response;

"My questions should be directed to Dynamic Tire Company in Ontario". ???
I inquired if I was to assume that Dynamic was the actual importer and TBC was the importer from the importer? They replied that Dynamic was their supplier. Dynamic also states they are importers of "value tiered" tires. So, what does that tell me? I have no idea. I decided to accept the little chart they sent as the latest greatest and let it go at that.

I do know that I've had no success whatever in finding a direct link to "Sailun" tires except TBC, and now Dynamic. I've always thought TBC was THE importer but now understand they are the importer from the importer I also realize that I am getting ready to head back to TX in a few days, the Sailun tires feel very robust compared to competitors, they have a great reputation and I'm digging in an empty rabbit hole. Just some trivia I thought I would share before I forget it.
There is no reason to have a load inflation chart from an individual tire manufacturer. All load inflation charts are standardized and approved by the tire and rim association (TRA).

Tire manufacturers do not set tire inflation pressures.

Replacement tires that do not conform to the Original Equipment tire designated size found on the individual vehicle certification label, have their recommended cold inflation pressures set by the tire installer. That inflation pressure must be set at a value that will allow the replacement tires to provide a load capacity equal to or greater than what the OE tires provided.

When deviations in inflation pressures are used/required, they start at the recommended cold inflation pressure for the OE tires and end at the tire maximum load listed on the tire sidewall. The USTMA uses these words when using deviation inflation pressures; "Never use inflation pressures below what was recommended for the OE tires".

Here is a standard load inflation chart. Notice that it was approved by TRA.
