I went out to the warehouse to measure the outside diameter of the center of the hub # 84546UC3. I used a set of digital dial calipers to take the measurement and came up with 2.6 inches in diameter at the widest point. The pilot hole on your trailer wheel would need to be 2,6 inches (or larger if the wheel is centered on the hub using lug nuts).
