You can use a smaller wheel on your trailer as long as it has the same bolt pattern and a hub diameter equal to or larger than the existing wheels and the weight capacity of the wheel and tire combination are compatible with the trailer and axle. Of course, you would need tires that fit the smaller wheel such as the Loadstar ST185/80D13 Bias Trailer Tire - Load Range D, # AM1ST79.

We do offer 5-1/2 inch wide rims, like # AM20304, if you wanted to replace your existing wheels. Or if you wanted a tire and wheel combo at the smaller size, we have the Loadstar ST175/80D13 Bias Trailer Tire with 13 inch White Wheel, # AM31233 (13 inch wheel by 4-/1/2 inches wide).

Just a word of warning. If you go with a tire and wheel too small you run the risk of bottoming out on bumps.
