The Kenda Karrier S-Trail ST145/R12 # AM10130 that you referenced is slightly smaller in diameter and slightly wider than your original 5.30-12 tire size, so the 145/80-12 tires will take up nearly the same amount of space and work well on your camper.

All of the 12 inch, 4 on 4 inch bolt pattern wheels that we offer have pilot diameters between 2.80 and 2.84 inches. The Dexstar Steel Spoke Trailer Wheel, 4 on 4 # AM20122 falls at the end of that range with a pilot diameter of 2.82 inches. The best way to know if this wheel will work on your trailer's hub is to use a caliper to take a quick measurement of the hub center to see if it is smaller than 2.8 inches (2-13/16 inches) so the wheel will fit over it.
