I have a 2016 27DSRL and went to Goodyear Endurance LR D 205/75/14 tires. It makes all the difference in the world in the towing experience. Rated to 81 instead of 60 mph (although I do not tow over 60 to 65mph), and an unexpected benefit was more stable (less bounce) when parked and in use.
I can't see the 15 inch wheel making that much difference and as already stated may change the whole dynamic of your rig.
