Do yourself a favor and listen to the folks here who have been there and done that. Put a new set of Sailun s637 on it and your tire issues should be over

Without a speed letter or written speed restriction molded on the tire sidewall they default to the antiquated TRA value of 65 MPH.
With a stiff tariff threat to the off-shore tire builders, The Trump administration forced tire manufacturers to use the speed lettering system which is standard for automotive tires. They were given the option to use the lettering system or mold the actual tire speed limit on the tire sidewall. To dated, the only RV trailer tire manufacturer I know of not in compliance is Maxxis.
Bottom line; tire speed ratings are what their manufacturer says they are. They cannot put a DOT certification on the sidewall without testing. Their testing method has been approved by NHTSA.
These pictures show the only two ways a tire manufacturer can display a tire’s speed rating.
