I might have a solution for you, but we do not carry any wheels that have a 4 on 4-1/2 bolt pattern. We do offer 13 inch wheels with the very common 4 on 4 bolt pattern which may be what you are measuring.

Since your wheel has an even bolt pattern you will want to measure the bolts that are directly across from each other center-on-center. I have attached a helpful article demonstrating this.

If your bolt pattern does turn out to be 4 on 4 then we have a variety of wheels for you to choose from.

If you have a trailer that is frequently getting wet, like your boat trailer, then I highly recommend going with the 13 inches x 4-1/2 inches Galvanized Rim # AM20224. The Galvanized material will help it withstand rust and corrosion better than normal wheels. This wheel has a weight capacity of 1,660 lbs, a pilot hole diameter of 2.65 inches, and a limited 2-year warranty.

If you are looking for a replacement wheel for a non-boat trailer then I recommend going with the Aluminum Split Spoke Trailer Wheel # AM22322HWT. This wheel measures 13 inches x 5 inches and is made out of aluminum to resist rust and corrosion better than steel wheels are. This wheel also has a weight capacity of 1,660 lbs, but has a different pilot hole diameter of 2.80 inches, and a lifetime warranty against structural defects.
