You can get some more load capacity, with the 225/75R15. You can find more of the 225/75R15's in a Load Range D (8ply rating) and Load Range E (10 ply rating).
Most of your 215/75R15 tires are going to be Load Range C (6 ply rated), but you may be able to find some in a Load Range D (but will probably be hard). Another thing is, a 215/75R15 size ST trailer tire is kind of an anomoly. A lot of manufacturers skip this size in their lineup. They go from a 205/75R15 directly to a 225/75R15.
This extra capacity may be overkill, but more can't hurt.
