This is a standard size 5 hole bolt pattern used on most factory made trailers. Measuring a 5 hole bolt circle is tricky because two bolt holes aren't directly across from each other on the circle. A trick to measuring 5 bolt wheels is measure between the centers of two side by side holes. On a 5 on 4.5" bolt circle it will measure exactly 2 5/8" from center to center of two side by side lug holes, see the picture. If you are attempting to measure bolt circle on a 5 hole wheel you would actually measure from the center of one hole straight across to where a hole WOULD be if located directly across and on the same circle. The center hole size is roughly 2 3/4" however the center hole does not have to be the exact same size as your hub. It just needs to be large enough to go over it so the wheel can seat flat against the hub. These trailer wheels are stud piloted, that is they center on the tapered face of the lug nuts or bolts when tightened not the center hole.
