What is the difference between the load rating D and E? I know mine are ST145R12 S-Trails but Im not sure which Load Range. Also is there a slightly wider tire I could use?

Load range D has a capacity of 1,220 lbs at 65 psi, whereas load range E has a capacity of 1,520 lbs at 80 psi. Basically the only difference between the two is the weight capacity. With trailer tires you always want to have them inflated to their maximum that way you get the best handling, braking and wear characteristics.

You should note that if you increase the load capacity of your tires it will not necessarily increase the overall capacity of your setup. You must always go with the lowest rated component in your towing setup as the overall capacity.

I attached a couple FAQ articles on trailer tires for you to check out also.

We do not have any wider tires that will fit your rims either.

The highest capacity 13" tire we have available is a Load Range D ST185/80R13 like the Kenda # AM10208. This radial ply tire features a maximum load of 1,710 pounds at 65 psi. We don't have any 13" tires in a Load Range E or F.

I was able to find the 126003 hub and was able to determine that it is a 3,500 lb hub/drum with a 5 on 4-1/2 inch bolt pattern just like the #AKHD-545-35-K that you referenced. This hub will work as a replacement for your Lippert.
