Trailer tire sizes ST145/80R12 and 5.30-12 both fit on 12 x 4-inch wheels and when mounted both will have similar overall diameters; 21.9-inches for a 5.30-12 like Kenda # AM30820 and 21.3-inches for an item like # AM31215.
We offer both of these tire sizes in several choices of Load Range. You can click on the links in the article I included for you see products in both tire sizes. Links to 5-on-4-1/2 wheels/tires in both sizes are provided for you.
Please note that size 5.30-12 is offered in bias ply tires only, while the 145 size is available in radial construction.
