As long as you have the needed clearance for the larger wheel and tire with part # AM32156 it would work just fine. It's going to be right at 5 inches taller than what you have and 3 inches wider.

Keep in mind you want at least 1 inch between the tire and the trailer frame and 4 inches from top of tire to the bottom of the fender.
