The difference of .9 on diameter is only .45 from axle to top of tire. If his wires are that close I would be very concerned with the existing tires.
From OP original post.
"1 do not want to increase height (as there are wires running over tire) so 235/85s are out. this leaves my options as:
245/75 or 225/75."

"I am kinda partial to the 245/75s as we freguently drive/park/camp on grass/dirt/etc. and spreading the load over a wider tire seems to make sense to limit (somewhat) sinking in."
At his weight, I believe he is over thinking this part. Wider is not necessarily the best thing for a trailer tire.
Both the 215/85R16 and 225/75R16 are a better match to his trailer weight than the 235/85R16 and 245/75R16. With the larger tires rated to 3042 he will need to run lower inflation, to prevent center of tread wear issues and beating up the trailer, which defeats the reason to install them.
