Bolt pattern measurement: The TRUE bolt pattern is the diameter of the circle ALL 5 LUGS are placed on, through the center of each lug.
The best way to measure this is shown in the diagrams below, refrencing the MEASURED BOLT PATTERN specifications.
A CHEVROLET bolt pattern will measure 4.5" between studs....this is still considered a 5-4.75 bolt pattern.
