Depends upon the size of the fenders (if so equipped), and the axle/suspension weight rating. It would be a big help if we knew how big the trailer was, and it's intended use.

Bigger is always better.It is easier to get more load capacity,they pull easier over uneven surfaces,dont sink in soft soil,and roll at a lower rpm,thus extending wheel bearing life.

What I was looking at is the bigger the wheel the higher the trailer sets.
The higher it sets the steeper the ramps going onto it.
On the other hand the lower the trailer is to the ground the more likely the back overhang can drag on something.
Always a trade off han't there?
I'm talking about a 16 footer to haul a BX23 on.

you can use dropped axels,or mount the axle above the spring to get it lower,add a dovetail to the trailer?

General duty 16' tandems typically have a pair of 3500# axles. That means each tire must be load rated at 1750# or more. The rim capacity must meet or exceed the tire capacity. That pretty much limits you to 14" or larger rims with no less than five or more bolt holes each.
Check out http://www.northerntool.com/webapp/wcs/stores/servlet/CatDsp?storeId=6970&N=124+1527&Ne=2 for a pretty good selection of trailer tire rim combos.

Most of the 13 inch rims I have seen have smaller center holes for lighter weight axles.
There is very little difference in overall diameter between a 205-75x14 trailer tire and a 205-75x15 trailer tire, and usually no difference in the load capacity

You should also consider the type of tires to be used too---true "trailer service" (radial or bias) versus passenger car tires. The thinner walled car tires tend to lend a "swishy" feel to the trailer at highway speeds loaded. I have tall radial 16" on my equipment trailer and it rides great with 12,000 on it. But don't put trailer tires on a vehicle--the ride will be bad (thicker side walls) and I'm told by a tire engineer, not safe especially when steering. And most tires are designed specifically for a particular model of car/truck for handling, ride quality, and suspension performance/wear.
And don't get me started on trailer axle and supsension types...
