As long as you keep the weight of your trailer below 3300lbs the Karrier ST175/80R13 Radial Trailer Tire - Load Range D # AM10210 would be an exact replacement that have a load rating of 1650lbs at 70 PSI.

For a tire that has a load rating higher than the GVWR of the trailer you will need to step up to a 14" wheel and use the Karrier ST205/75R14 Radial Trailer Tire - Load Range D # AM10235 which has a load rating of 2200lbs at 75 PSI. This tire will be 2.2" taller overall and 1" wider overall so you will need to make sure your trailer has enough clearance.

You will need to measure from the top of your current tire to the bottom of the fender, and from the inside edge of the tire to the frame. As long as you have at least 4" - 5" from the top of the tire to the fender and 2" from the inside of the tire to the frame the larger SR205/75R14 will fit without any issues.

This will require you to replace your wheels, so you will need to measure the bolt pattern of your current wheels first. I included a link to a helpful article that goes over measuring your bolt pattern and a link to all of our 14" wheels for you to take a look at.

I also included videos for both of the tires mentioned for you to take a look at.
