The Karrier ST205/75R14 Radial Trailer Tire part # AM10234 or part # AM32156 with galvanized wheel has a load range C rating which is suitable for use up to 1,925 lbs. If you take this number and multiple it by the number of tires you should get about 10-15% less the GVWR of the trailer. The reason this figure won't exceed the GVWR is you must still factor in the weight that gets transferred to the vehicle via the tongue (i.e. tongue weight). The total weight capacity of trailer tires will almost never exceeds the GVWR of the trailer from the factory.

That said, I simply recommend sticking with the same size and load range as the tire equipped on the trailer at the factory so you don't run into issues like a rough ride from over rated tires or not enough capacity from under rated tires.
