I have a solution for you, but the # AM20422 is a 15" x 5" wheel, which is going to be slightly too narrow for a 235/75/R15 tire. In order to fit a tire of that size you would need at least a 6" wide wheel like the # AM20522, but there may be some issues with using the tires you mentioned since they're designed for passenger vehicles and not a trailer.

Typically, you won't want to use a tire with the P- prefix on it as those are designed for passenger tires and not for trailers. Trailer tires are designed for load bearing, so I do recommend going with something like the Provider ST225/75R15 Radial Trailer Tire - Load Range E # TR225LRE which will fit on the above mentioned # AM20422 wheels. These tires are only .3" smaller than the 235/75/R15 tires you mentioned, and since they're designed for use on a trailer, they're a much better solution.

I've linked some helpful articles that we have done that you might find helpful, but I do recommend at the very least making sure that any new trailer tires you purchase have the ST prefix on them since they will be designed for the load bearing requirements.
