Question:

Callico horse trailer 6 bolt wheels will the 6 bolt 5 1/2 fit all style wheels? I would a assume that they just snap over the lug nuts. I would also assume that the 5 1/2 would be measured from center to center.

You are correct the Quick Trim Chrome Finish Trailer Hub Cover 6 on 5-1/2, item # QT655C, just snaps over the lug nuts.

As far as measuring the 6 on 5-1/2 bolt pattern you can measure directly across the wheel from the center of one hole in the wheel to the center of the hole directly across from it. For 6 on 5-1/2 you should get a measurement of 5-1/2 inches. See the picture to the right of where to measure to get the bolt pattern of a wheel.

I am including a link to a FAQ page on measuring the bolt pattern of a wheel.
