What is and how do I measure the 120 mm dimension on our wheels? Is it between studs? Is it across studs? Is it the diameter of the "circle"? What is it please?

Its the measurement of the circle created by the centerline of the studs. 5 lug isnt as easy others.

Here is a link from tirerack that explains it:


It should be from the centerline of the stud to the circle directly across from it but you can get close to the same reading by measuring from the centerline of the stud to the back of one of the studs across from it.
