Yes, The Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10130 will fit the same 12 inch wheel with a 4 inch width that your existing 4.80-12 size tires are mounted to.

The ST145/R12 tire will be about 0.8 inches larger in diameter, so you will want to make sure you have the necessary clearance on your trailer for the slightly larger tires.

The Kenda radial tire has a ply rating 8 and has a maximum load at 1,220 pounds at 65 psi. The maximum speed of the tire is 81 mph with a speed rating M.
