A four stud wheel can be measured from the inside of one hole directly across to the outside of the hole opposite. This is not possible on 5 stud wheels.

To measure P.C.D. on a 5 stud wheel, measure from the inside of one hole to the outside of the next hole. Then calculate P.C.D. using the chart below.
