Special Trailer tires are designed for service on any sort of trailer.
The design characteristics between the two differ considerably. So will the building materials, compounds and formulas. It's why the ST tires have higher load capacities than like sized tires of other designs.
However, the basic argument often centers on their passenger carrying abilities. Twenty-two states currently allow RV trailers to carry passengers. It's not dependent on the tires ability to carry passengers but the safety factor. All DOT highway certified tires are approved for passenger service.
