5-LUG Measure from the center on one hole to the BACK of the third hole.
This is the easiest  way to "Guesstimate" a 5-lug bolt circle.  

TO VERIFY THIS --  DRAW A CIRCLE TO THE EXACT DIMENSION OF THE GUESSTIMATED BOLT CIRCLE AND CUT IT OUT -- PLACE THIS CIRCLE EVENLY ON TOP OF ALL 5  STUDS --- THE OUTSIDE OF THE CIRCLE SHOULD LINE UP WITH THE CENTER OF ALL 5 STUDS --  IF NOT  --( GUESSTIMATE AGAIN AND REPEAT PROCEDURE )
6-LUG Measure center to center of two holes directly across from each other.
8-LUG Measure center to center of two holes directly across from each other.
