Replacing Trailer Tires

[MNChampion]

I have some flat-spotted, worn out tires on my trailer. They are Firestone Super Sports and F70-14 in size. I am having a difficult time finding replacement tires. I have been looking on-line at tire size converters and am getting multiple sizes, from 205 to 225 that supposedly fit. Has anyone replaced F70 tires? If so, what did you replace them with?

Not sure this will help at all, but my tires are 205/75R14 and say that they replace F78-14 on them.

And these guys get pretty detailed in their conversation relating to F70-14s:
