If the tires on your trailer are the 175/80-13 size and the wheels have a 5 on 4-1/2" bolt pattern then the Karrier ST175/80R13 Radial Trailer Tire # AM31994 with the galvanized wheel will fit. This combo have a load range D which is 1,610 lbs at 65 psi and has a max speed rating of 81 mph.

The galvanized finish on the wheel is perfect for marine applications. It is a bit of a rougher finish and helps to keep the steel wheel from rusting and corroding.

If you would rather stick with a white wheel like what you currently have then you would need part # AM31985 instead. This has the exact same specs as the part you mentioned, it just uses a white wheel.

The 5 on 4-1/2" bolt pattern is pretty standard, but if you are unsure whether that is what you have or not you can check out one of the linked review videos, the helpful article, or just check out the picture that I added to this page.
