Measuring bolt pattern?

[kdlklm]

How do you measure a 6 lug bolt pattern. Is there any special way. Or does anyone know the measurements for a Kubota B5100e. I am planning on a getting another set of tires and rims rear tires only.

6 lug is easy........measure form the center of bolt 1 to the center of bolt 4. I think /forums/images/graemlins/grin.gif
