Expert Reply:

Trailer tires that are the same size but with different load ratings will have different capacities. A load range C tire will have a higher capacity than a load range B tire of the same size. The Kenda 4.80-12 Bias Trailer Tire with 12 Inch White Wheel, # AM30660, that you have referenced has a capacity of 990 pounds at 90 psi and it is a load range C.
