In a 12-inch rim size with a 5-on-4-1/2-inch bolt pattern we offer a range of pre-mounted wheel/tire combinations in both bias ply and radial types and in several different load ranges. The link provided will let you see all such combinations, which include 145/80-12, 4.80-12 and 5.30-12 tire sizes. I also linked an article on trailer tires that may be helpful.

Please note that all of these tire sizes are a 4-inch width. The highest-rated among them is the Load Range D combination, part # AM31202 from Americana, rated for 1520-lbs at 80-psi inflation.

If you need a load range E, you would need to purchase the wheel and tire separately and have them mounted at a local shop upon arrival. For this, I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range E # AM10140 and the Aluminum Lynx Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - Silver # LH45FR.

Please note that changing to higher-rated tires will not increase the weight capacity of your trailer. Also, a wider tire/wheel may pose clearance issues with your trailer's frame and/or fenders.

If the wheels/tires on the trailer now are not the original/correct size then I suggest you determine the axle capacity (there should be a label on the axle) before selecting new wheels/tires.
