In order to find a tire to replace the size you currently have, you may want to consider a tire/wheel combo replacement. The tires you have on your trailer measure about 20.4 inches tall so to make sure your replacements fit with your fenders you want to stay as close to that as possible.

The tires we offer that are closest to the size you have are the 4.80-12 tires. We offer the tires separately and we also have tire/wheel combos that may work for you.

We will need to know the bolt pattern on the hubs you currently have. I have attached a helpful article that explains how to take that measurement.

If you find you have a 4 on 4 bolt pattern I recommend a combo like part # AM30620. This is a Load Range C combo that measures 20.7 inches when inflated. This combo has a maximum load rating of 990 lbs at 90 psi. The wheel has a diameter of 12 inches and is 4 inches wide.

For a combo with a 5 on 4-1/2 bolt pattern I recommend part # AM30660. This combo also measures 20.7 inches diameter when inflated, and has a wheel rim that measures 12 inches diameter x 4 inches wide.

The 13 inch tires we offer measure over 24 inches, which may have a problem with clearance with the fenders you said you have installed.
