The two tire sizes you referenced, 4.80-12 and 5.30-12, both fit 4-inch wide rims, but they differ in their overall diameter. A 4.80-12 tire/wheel when fully inflated will have a diameter of 20-1/2-inches while the 5.30-12 size will be just under 22-inches in overall diameter. As long as the additional height is not a problem it would be a great choice if you wanted to swap to the bigger size.

The part # TT53012C would then be a great choice as a replacement. This has a 1,050-lb max load at 80 psi and a speed rating of 81 mph.

You really want to have your spare and trailer tires the same size.
