Question going from 15" to 16" tires
I will be upgrading to 16" but am a little concerned about distance between the front and rear tires. With the current 225/75/15's, I have roughly 4 1/4" clearance between the tires. With 235/85/16'...

We don't have a real heavy trailer and don't do real long trips, so I'm not worried about them whatsoever. I do plan on getting a TPMS system to go with them.
All ST tires have more load capacity the a same size LT tire.
However that in itself doesn't mean much as far as long term reliability which is one of the bigger reasons many trailer owners (rv and non rv ) use a LT class tire that meets the trailers axle requirements at a minimum.
Good idea on a TPMS system if running a ST E/D/C poly carcass tire.
ST tires simply have close to zero "reserve" capacity, they just rate them right to the edge of their design. LTs, since they are passenger rated, have a safety "reserve", which is, more or less, a down-rating of their max design capacity, to give more "reserve". I was told decades ago, by 3 or 4 auto-engineer types (mostly from the GM Proving Grounds) that passenger tires have about a 25% "reserve" load capacity over the sidewall rating.
