I have 5,200 lbs axles on my trailer, it came stock with Kenda Loadstar tire marked 113 108M. What load class tire do I need. Class D or E?

If you are wanting to stick with Kenda tires with the ST225/75R15 size then you will need to go with the Load Range E # AM10303. You always want your tires to be rated for at least the same weight as your axles. The Load Range D # AM10256 has a weight rating of 2,540 lbs at 65 psi which means when using 2 of them your max weight is 5,080 lbs. The Load Range E has a weight rating of 2,830 lbs at 80 psi which means that 2 of them have the combined rating of 5,660 lbs making your 5,200 lb axles the lower rated components.

The tire and wheel combo # AM32664 you referenced has the Load Range D tire so for the Load Range E tire on the same white wheel you would want part # AM32680 instead.
