The Continental Vanco 8 is a suitable commercial truck and trailer (not ST) tire which is made in Load Range D, in similar sizes such as 205/80R14. That particular size is almost an inch taller than a 205/75-14 and possibly closer to the original size on trailers such as my B1700, which came with an F78-14 tire in 1979.
I don't know how readily available the Vanco 8 is.
All ST tires in the same size and load range will have the same load capacity, so I assume that Bob's intention is to find a tire with a higher load capacity than that of an ST205/75-14 LR-C.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.
