Count the number of lug holes or wheel studs
Measure the bolt circle diameter if the wheel has an even number of lugs
Measure from the center of one lug hole to the center of the opposite lug hole for even patterns
Measure from the center of one lug hole to the outer edge of the farthest lug hole for odd patterns
Use a bolt pattern gauge for the most accurate measurement
Check the vehicle owner’s manual or manufacturer specifications
Match both the lug count and bolt circle diameter when comparing wheels
Verify the pattern before buying or installing wheels
