Just purchased a set of Sailun tires for my fiver. I contacted Alan Eagleson at Sailun tires and requested the load/inflation tables. He sent me both for the ST235/80R-16 and ST235/85R-16 tires. It is a PDF file.

Yes that PDF is a scan from the US Tire & Rim Association 2016 yearbook. This chart would be used by almost all tire companies.

Thanks for the load rating table. My Sailun tires, S637 ST235/85R16 load range G, on my 2016 bighorn are rated at 3750 lbs @ 110 psi (stamped on the side of the tire). The table says 4400 lbs @ 110 psi. I must be missing something.
Can you capture pictures showing the tire size and the Load information. Also the full DOT serial (including the date code )
Tires are suppose to follow DOT regulations. Those regulations point to TRA published standards. Possibly a mis-production. Could be subject to a recall

There are 2 versions of the Sailun S637; one certified as a passenger LT tire and the other as an uncertified ST trailer tire. The stamping of the sidewall may be the only difference. LT certification requires a safety margin that's not required for ST tires. So an ST tire can be sold with a higher load capacity even though it's the same as the LT tire.
Sorry but someone is giving you some confused information.
1. ALL DOT tires are "Certified" by the tire company to be able to pass certain regulatory requirements. Part of those requirements include the size & type % load rating information.
2. Passenger tires use the letter P before the section width i.e. P235/75R16 LT tires would say LT235/75R16 and ST tires would say ST235/75R16
3. I know of no place in the Federal DOT regulations where a company can mark a tire "LT235/75R16" and then call it an ST or P type tire
4. Where can I find a reference to the "safety margin" you are talking about. The DOT regulations are "minimum" performance standards. There are no Plus or minumtolerances on the minimum requirements.
