To determine if you will be able to switch from your Loadstar 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30670 to a Loadstar ST175/80D13 Bias Trailer Tire with 13" Galvanized Wheel # AM3S060 you will need to verify the wheel bolt pattern and ensure you have enough clearance for the larger tire. As there are different size 5 lug patterns you will need to either measure your bolt pattern or remove the wheel to find the bolt pattern measurement stamped inside. The 5 on 4-1/2" pattern is the most popular pattern. The easiest way to verify this measurement with the wheel on the hub is measure from center of wheel stud to the center of the next closest wheel stud. A 5 on 4-1/2" bolt pattern will be 2-5/8" on center.

To determine if you have enough clearance you will need to account for the additional 1.7" of width and 3.3" in diameter of the larger tires. Tires should have 1" clearance on the side wall and 3" of vertical clearance for the suspension to travel. So with your current tires you will want 1.9" of clearance on your side walls and 4.7" of vertical clearance.
