I'm a little confused at what you're saying. If you're looking at tire/wheel sizes on a trailer at a RV show they should be Original Equipment tires/wheels. Unless the trailer manufacturer authorizes the use of optional designated sizes the prospective consumer MUST accept the OE tire designated size. Brands are another subject.
The FMVSS standard reads in part: The designated tire size on the trailer at the time of first sale MUST be the same designated size as those listed on the federal certification label. I assume the designated size you have mentioned is ST235/85R16?
If you're questioning the tire separation between axles as installed, 1" is the minimum.
