Very true. I suppose the question is not "what is the original tire size", or even "what tire size is currently on the trailer", but rather "what size should be used on this trailer"... which may depend on what has been done to it.
With a 3500 pound axle
, ST205/75R14 LR-C would be adequate, would be readily available, and would fit. A larger size may be more optimal, and the currently installed size may indicate what can fit.
